## Why Automate Image Generation?

If you're manually creating dozens of similar images—like product cards, social banners, or personalized emails—automation can save you hours of repetitive work. Just set up a template once and let Zapier take care of generating images for new data entries.

The basic idea is to automatically **replace parts of your image template with new content**, such as names, prices, images, or dates. This is perfect for:

- Personalized email campaigns
- E-commerce product visuals
- Blog or social media graphics

Let’s walk through an example using RenderForm + Zapier + Tally forms.

---

## How to Automate Image Generation with Zapier

Zapier makes automation easy. In this case, we’ll set up a three-step workflow:

1. Set a trigger (e.g. a new form submission),
2. Create an image template in RenderForm,
3. Configure the image generation in Zapier.

Let’s go through it step by step.

### Step 1: Set the Trigger Event

We’ll start by creating a **trigger** that will launch the image generation process. This can be anything—from a new lead or calendar event, to a form submission or database update.

![Create event with Tally](/blog/zapier-trigger-event.jpeg)

In this example, our trigger will be a **new form submission from [Tally](https://tally.so)**.

1. In Zapier, create a new Zap.
2. Set **Tally** as the trigger app.
3. Connect your Tally account and select the form you want to use.
4. Let Zapier test the connection to make sure data can be pulled correctly.

**What’s the use case?** I created a simple Tally form that gathers details needed to create a hotel offer for a client—like hotel name, dates, price, and availability.

![Tally form](/blog/make-tally-form.jpeg)

---

### Step 2: Design Your Image Template in RenderForm

Next, we’ll create an image template in RenderForm. Each editable field in your template—like `price`, `title`, or `image`—will act as a dynamic component that Zapier can update automatically.

![Create image template in RenderForm](/blog/make-renderform-template-l.jpeg)

In this example, I’ve created components for the hotel name, price, availability, and main image. Each time the form is submitted, these fields will be replaced with the corresponding values from Tally.

---

### Step 3: Create the Image in Zapier

The final step is to connect **RenderForm** to your Zapier workflow and configure the image generation.

1. Add a new action to your Zap.
2. Choose **RenderForm** and select the **"Create Image"** action.
3. Connect your RenderForm account using your [API key](https://renderform.io/console/api-keys/).

![Add RenderForm event in Zapier](/blog/zapier-renderform-apikey.jpeg)

Now configure the image generation:

- **Component Name** – On the left side, enter the component name and type, e.g. `price.text` (to target the `price` component of type `text`).
- **Form Field** – On the right side, choose the corresponding Tally field that should populate the image component.

![Set up RenderForm image generation](/blog/zapier-renderform-setup.jpeg)

Repeat this process for each element you want to update dynamically in your image.

---

### Test and Run the Automation

Once your Zap is configured, save it and let Zapier run a test. If everything is set up correctly, you’ll get a **new image generated from your form submission**—complete with all the personalized details.

![Image generated automatically](/blog/make-renderform-image.jpg)

Don’t forget to **turn on your Zap** so it actively listens for new submissions.

That’s it! The entire setup takes just a few minutes, and the results can dramatically speed up your workflow.

---

## Ideas & Use Cases

Once you’ve got image generation working, here are a few creative ways to expand your workflow:

- Automatically generate social media graphics for new blog posts
- Create custom product cards with prices from Google Sheets or Airtable
- Generate dynamic banners for newsletter emails
- Use screenshots to document website changes or generate content previews

You can even **chain Zapier actions** together to upload generated images to Google Drive, send them via Slack, or publish them online.

Image Generation with Zapier


Do you often forget team members' birthdays or struggle to send greetings on time? You are not alone. Even in the most thoughtful teams, birthday wishes can get lost in the chaos of deadlines and meetings. But what if you could automate it — and still make each message feel personal and warm? 

In this post, you will learn how to build a simple no-code automation that sends personalized birthday cards to your team on Slack using Google Calendar, [Zapier](/blog/posts/image-generation-with-zapier) (or even [Make.com](/blog/posts/image-generation-with-make)), and RenderForm.

## 🎯 TL;DR: What you'll learn

- Track team birthdays with a dedicated Google Calendar
- Auto-generate personalized birthday card images using RenderForm
- Send cards automatically to Slack with Zapier
- Create a scalable, no-code workflow for team celebrations

## Why automate sending birthday cards

Automating the process of sending birthday wishes is a great solution for various reasons:

- You never forget to send wishes, even during busy times.
- Enables scalability, allowing you to send personalized wishes to many recipients simultaneously.
- Saves time and effort by eliminating manual intervention.
- Maintains consistency in your birthday greetings.
- Allows for scheduling and customization in advance, creating a seamless and heartfelt experience for recipients.

Automating birthday wishes makes the process easier and more enjoyable for you. By saving time and effort, automation allows you to spend more quality time with the birthday person. It simplifies the process and lets you focus on the personal aspects of celebrating their special day.

## Birthday wishes automation

The automation we are going to build works great especially for workspaces and teams. The automation combines the power of three platforms:

- [Google Calendar](https://calendar.google.com/): Utilizing Google Calendar, we will **create a dedicated calendar** to keep track of team members' birthdays.
- [RenderForm](http://renderform.io): With RenderForm, we can easily **generate personalized birthday cards**, ensuring a unique touch for each individual.
- [Zapier](http://zapier.com): By harnessing the capabilities of Zapier, we can seamlessly **connect these apps** and effortlessly send birthday messages and corresponding images to the designated Slack channel.

The end result is simple yet impactful. The birthday person will receive a personalized card filled with warm wishes directly on the selected Slack channel. With this automation in place, celebrating team members' birthdays becomes a breeze, fostering a positive and engaging work environment.

## Create and setup Google Calendar

To begin, let's create a new calendar in Google Calendar specifically dedicated to birthdays. Follow the steps outlined in [Google Support's help base here](https://support.google.com/calendar/answer/37095) to create the calendar effectively.

After creating the calendar, we need to populate it with the actual birthdays of our team members. Here's how you can do it:
1. Add event to your calendar (set event time to hour that aligns with when you want the birthday message to be delivered.)
2. Add the birthday person's name as the **event title**.
3. Set the event to **repeat yearly** to ensure it recurs automatically.
4. In the **description**, include a short personalized birthday message that will be added to the birthday card.
5. Ensure that you select the **Birthdays calendar** you created.
6. Set the event as **Free** to avoid affecting your real work calendar availability.

![Creating birthdays calendar in Google](/blog/birthday-cards/birthday-google-calendar.png)

This step may require some initial effort, but remember that it is a one-time task. You may already have some birthdays in your calendar, which can save you time. Once you have completed adding the necessary birthdays, you're ready to proceed to the next step!

> Once the calendar is ready and filled with birthday dates, you can choose to **hide the calendar** to prevent it from impacting your regular work calendar. This way, you can maintain a clean and organized view while still benefiting from the automation.

## Create birthday card template

Now, let's dive into the exciting part of creating a personalized birthday card using RenderForm. This card template will serve as the foundation for the automated birthday wishes, allowing you to customize selected image elements for each recipient.

![Creating birthdays calendar in Google](/blog/birthday-cards/happy-birthday-slack.jpeg)

To begin, log in to your RenderForm account or [sign up for free](/register) if you don't have an account yet. Navigate to **My templates** and start creating your unique birthday card template. With the RenderForm Template Editor, you have the flexibility to incorporate various elements such as **backgrounds, images, emojis, custom shapes, and more**.

For my birthday card template, I've included specific elements that I want to personalize when the card is sent to different individuals:
- birthday person's name (`name`)
- custom text with wishes (`wishes`)

On the left side of the editor, you'll find all the **template elements (components)**. In addition to the mentioned elements, there's an image, background rectangles with colors, emojis, background circles, and other decorative elements.

![Components of the birthdays card template](/blog/birthday-cards/birthday-template-components.png)

> **Tip 1:** Rename the [template components](/docs/general/template-properties/) to easily identify them later during image automation.\
> **Tip 2:** Lock elements that you don't want to change during image generation. You can do this by clicking on the lock button in the element properties panel.

Once you've crafted your template to perfection, remember to save it. Now, you're ready for the final step: creating the automation.

> Want to send cards to a larger group at once? Check out our guide on [how to generate multiple images with different texts](/blog/posts/how-to-generate-many-images-with-different-text) — perfect for batch greetings.

## Create the automation

In this final step, we'll create and configure the automation using Zapier, which will seamlessly connect all our apps and facilitate the automated birthday message delivery to the selected Slack channel.

To get started, log in to Zapier and create a **new Zap** by following the instructions below.

### Setting up the Trigger from Google Calendar

The trigger event will be an event from our birthday calendar, which will initiate the desired action when a birthday is detected.

#### App & event

Choose **Google Calendar** from available apps and select **Event Start** as the trigger event.

![Setting up Google Calendar as trigger in Zapier automation](/blog/birthday-cards/birthday-automation-zapier-trigger.png)

#### Account

Connect Zapier with your Google account to grant it secure access to your calendar. Rest assured, your calendars will not be shared anywhere.

![Connecting Google Calendar to Zapier](/blog/birthday-cards/birthday-automation-connecting-calendar.png)

#### Trigger

Now, it's time to specify the trigger event. Start by selecting the **Birthdays calendar** where you've added all the birthdays in your Google Calendar. Next, set up the **Time Before** and unit (I recommend setting it to 30 minutes, which means that Zapier will check for triggers 30 minutes before the birthday event and initiate the automation accordingly). Click **Continue** when you're done.

![Setting up calendar trigger in Zapier](/blog/birthday-cards/birthday-automation-zapier-trigger-setup.png)

#### Test

The final step in this part is to test the trigger connection. Simply click on **Test trigger** and wait for the results.

![Testing the trigger in Zapier](/blog/birthday-cards/birthday-automation-zapier-trigger-test.png)

Once the test is completed successfully, click on **Continue** to proceed to the second part of the automation: connecting with the RenderForm birthday card template.

### Action: Link RenderForm template

In the action phase, we'll connect the birthday card template created in RenderForm with the event details from Google Calendar. This will involve using the event title as the birthday person's name and the event description as the personalized wishes.

#### App & event

Search for RenderForm in the list of apps and select **Create Image** as the event.

![Setting up RenderForm as action in Zapier automation](/blog/birthday-cards/birthday-automation-renderform.png)

#### Account

Connect Zapier with your RenderForm account to gain access to your templates and enable image automation.

![Connecting RenderForm to Zapier](/blog/birthday-cards/birthday-automation-renderform-connect.png)

#### Action

In this step, we need to specify how we replace the components in our birthday card template. As a reminder, we'll be replacing the `name.text` and `wishes.text` components from our template. The birthday person's name can be found in the Google Calendar event as the **event title (Summary)**, and the wishes can be obtained from the **event Description**.

![Setting up RenderForm action in Zapier](/blog/birthday-cards/birthday-automation-renderform-action.png)

#### Test

Next, Zapier will conduct a test to ensure the connection is working correctly. Click on **Continue** and then select **Test action**.

![Testing RenderForm action in Zapier](/blog/birthday-cards/birthday-automation-renderform-test.png)

Once the test is completed, you can **check the test image in the test result**. Open the image link in a new tab in your browser and verify if everything appears as expected.

![Test result with generated test image](/blog/birthday-cards/birthday-automation-renderform-result.png)

Now, instead of publishing our Zap, we need to add one more action: connecting our Slack channel, where the birthday cards will be sent automatically.

> You can also trigger [image generation directly from a spreadsheet](/blog/posts/how-to-create-many-images-from-spreadsheet), if you manage birthdays there instead of Calendar.

### Connect Slack channel

The last step in creating the automation for sending birthday cards is to deliver the actual message and image on Slack. This step follows a similar process, as outlined below.

Begin by adding a new action to our Zap and proceed with the configuration.

#### App & event

Search for Slack in the list of apps and select **Send Channel Message** as the event.

![Setting up Slack as action in Zapier automation](/blog/birthday-cards/birthday-automation-slack.png)

#### Account

Connect Zapier with your Slack account to access Slack channels and enable automated messages.

![Connecting Slack to Zapier](/blog/birthday-cards/birthday-automation-slack-connect.png)

#### Action

In this step we create the message that is sent to Slack. For that we need to:

- select the Slack channel where you want to send the birthday card
- create a message with text and incorporate the RenderForm action result, which is the auto-generated birthday card image

In the message, you can add additional text (optional) and choose the RenderForm action result, which is the automatically generated birthday card image.

![Setting up Slack action in Zapier](/blog/birthday-cards/birthday-automation-renderform-action.png)

> You can also personalize the message content! Utilize the birthday person's name from the event title to give it a personal touch!

#### Test

To ensure everything is functioning properly, run one final test.

![Testing RenderForm action in Zapier](/blog/birthday-cards/birthday-automation-renderform-test.png)

#### Publish Zap

Finally, after conducting the test, click the **Publish** button. With that, our birthday card automation is ready to go!

## Birthday card automation test

Before the automated sending of real birthday cards, it's important to perform a test to ensure that everything is set up correctly. Here's how you can do that:

**1. Create a birthday event in your "Birthdays" calendar**, scheduled for now plus 40 minutes. For example, if it's currently 9:00 AM, set the event to start at 9:40 AM. This allows Zapier enough time to run the trigger.

**2. Wait for the trigger to activate** in Zapier. The trigger will check the calendar for any upcoming birthdays.

**3. Check the result** on your designated Slack channel. You should see the automated birthday card message with the personalized wishes and image.

By performing this test, you can ensure that the automation is functioning correctly and that the birthday cards are being sent as intended.

![Test result for birthday card automation in Slack](/blog/birthday-cards/birthday-card-automation-test.jpeg)

## Conclusion

With this setup in place, you will never miss a team birthday again, and you will do it with style. Try it out today, and give your team a reason to smile on their special day.

**Image generation** is the process of creating visuals using automated tools, often based on a predefined template. Instead of designing graphics manually every time, image generation lets you reuse layouts and update only the dynamic parts like text, colors, or images.

Design software like Photoshop or Canva is great for one-off projects. But when it comes to creating hundreds of consistent, branded images, **automation** becomes essential. Tools like **RenderForm** make it easy to design once and generate unlimited variations using data from APIs or no-code platforms like Zapier, Make, or Google Sheets.

> RenderForm is built for speed, control, and consistency. Unlike AI art tools that rely on prompt engineering and randomness, it generates exact results based on your template. It's ideal for marketing, personalization, or bulk content creation.

## 1. Build a template with the editor

Start with the [RenderForm Template Editor](/docs/general/template-editor/). It works like a simple design tool: drag in text, image placeholders, or shapes, and arrange them however you like.

![Online Editor for Image Generation](/blog/simple-online-design-editor.jpeg)

### Set image fit

For image placeholders, choose how the image should behave inside the container. Click on any image and use the panel on the right to adjust the "Image Fit" option:

- `Cover` fills the entire space, cropping the edges if needed.
- `Contain` keeps the full image visible, even if it doesn't fill the entire space. Best for logos or product photos.

![Image fit options](/blog/image-fit-options.jpeg)

### Resize text areas

Text auto-scales to fit its container, but large or dynamic content might need extra space. Set the **width** and **height** manually to avoid clipping and keep everything legible.

Additionally, you can adjust the **dynamic font size limits** to ensure text remains readable across different lengths. This is especially useful for names, titles, or descriptions that vary in size.

![Text font size settings](/blog/text-font-size-settings.jpeg)

### Align text precisely

In the side panel, scroll to the Alignment section to define how text should wrap or stretch. This is useful for things like dynamic names, titles, or product descriptions that vary in length.

![Text alignment](/blog/text-component-alignment.jpeg)

## 2. Connect data to generate images

Once the layout is ready, it's time to connect it with data. You can use [RenderForm's REST API](/image-generation-api/) directly, or connect to platforms like:

- [Zapier](https://zapier.com/mcp/renderform) - Trigger image generation from forms, CRMs, or other tools
- [Make (Integromat)](https://www.make.com/en/integrations/bannerly) - Link multiple services and schedule image creation
- [Google Sheets](/blog/posts/how-to-create-many-images-from-spreadsheet) - Use spreadsheet rows as input for bulk image creation
- [Airtable](https://airtable.com/marketplace/blkKg8IYzQuTV6ZH3/render-form) - Generate images from Airtable records
- [Custom scripts](/docs/api/get-started) - Send image generation requests using your own backend

![Layout plus Data equals your image](/blog/image-generation-api.jpg)

The key is simple: update specific components in your template using a property format like this:

```
yourComponentId.property=value
```

Example:

```
headline.text=Summer Sale Ends Tonight!
```

This tells RenderForm exactly what to change inside the template. You can change text, image sources, colors, and more. See the full list of properties in the [template properties guide](/docs/general/template-properties/).

![Example of generated image from Image Generation API](/blog/example-of-generated-image-from-image-generation-api.jpg)

RenderForm processes the data and generates your final image instantly, ready to be used anywhere.

## Common use cases

Image generation isn't just about saving time, it unlocks new ways to deliver content with precision and consistency. Here are a few practical examples:

- **E-commerce**: Generate product images with live pricing, stock levels, or promo tags
- **Marketing**: Create personalized banners for ads, email, or landing pages
- **Social Media**: Automate quote cards, announcements, or seasonal visuals
- **Hiring**: Share branded job posts or team intro graphics for new hires
- **Events**: Generate speaker cards, schedules, or reminder graphics from spreadsheets or databases

Every visual stays on-brand, with no manual editing required.

## Why use RenderForm?

RenderForm helps teams produce image content faster without sacrificing quality or control. Design a layout once, then use automation to create thousands of variations with zero manual work.

Key benefits:

- ✅ Predictable, design-safe results
- ⚙️ API and no-code integration options
- 🎨 Full control over layout and visual style
- 📊 Perfect for personalized or data-driven visuals
- ⏱ Real-time generation—no delays
