What is AI Image Generation Action in Workflows?

The AI Image Generation action, available under AI Actions in Workflows, lets you generate images using AI models directly inside your automation. You provide a text prompt describing the image you want, choose a model and quality level, and the action returns a generated image stored at a publicly accessible URL. Generated images are saved automatically in Media Storage and are available as variables in downstream actions – so you can attach them to emails, send them over SMS, post them to social channels, or pass them to external systems.

Key Benefits of AI Image Generation Action

Multiple AI Models: Choose from a range of image models to match your quality, style, and speed requirements.
Prompt Enhancement: Refine a rough prompt into a detailed one with a single click, producing noticeably better output.
Ready-to-Use Templates: Start from a pre-written prompt for common formats like product mockups, social posts, promo flyers, and lifestyle imagery.
Brand Consistency: Apply your existing Design Kit and Brand Voice to keep generated images aligned with your brand.
Dynamic Prompts: Build prompts from custom values so each contact, product, or webhook payload produces a different image.
Automatic Storage: Every generated image is saved to Media Storage at a publicly accessible URL, ready to use anywhere.

Action Details

Field	Description
Action Name	A custom name for the action, used to identify it on the workflow canvas and in execution logs.
Model	The AI model used to generate the image. See the Model options list below.
Quality	The generation quality level. Options are Auto (default), High, Medium, and Low.
Prompt	A text description of the image you want to generate. Supports custom values, so you can build dynamic prompts from contact fields, webhook data, or previous action outputs.
Templates	Pre-written prompts for common image types. Selecting one pre-fills the prompt field, which you can then edit.
Additional Settings	Optional controls for size, background, output format, Design Kit, and Brand Voice. See the Additional Settings section below.

How to Use the AI Image Generation Action

Step 1: Add the Action

Go to Automation > Workflows.
Create a new workflow or edit an existing one.
In your workflow, click the + icon to add a new action, then find AI Image Generation under AI Actions and select it. Give the action a clear, descriptive name so it’s easy to identify on the canvas.

Step 2: Select the Model

Inside the prompt section, choose the AI model you want to use for generation. The following models are available:

GPT Image 2
Gemini 3 Pro Image (Nano Banana Pro)
Gemini 3.1 Flash Image (Nano Banana 2)
Gemini 2.5 Flash Image (Nano Banana)

Different models produce different visual styles and handle text-in-image, photorealism, and composition differently. If you’re not sure which to pick, try the same prompt across two models and compare the output.

Step 3: Set the Quality

Click the quality selector to open the quality options.

By default this is set to Auto, which lets the system pick an appropriate level for your prompt. You can also explicitly choose High, Medium, or Low.

Higher quality produces more detailed images but takes longer to generate.

Step 4: Write the Prompt

In the prompt input box, describe the image you want to generate.

Be specific about the subject, style, setting, lighting, and composition – more detail generally produces better results. The prompt field supports custom values, so you can insert contact fields, webhook data, or output from previous actions to build dynamic prompts.

Click the Enhance Prompt button above the prompt input box to have AI expand and refine what you’ve written. This adds detail around style, lighting, and composition that you might not have specified, and typically produces noticeably better output. You can edit the enhanced prompt further before saving.

Step 5: Start From a Template (Optional)

Instead of writing a prompt from scratch, you can start from one of four templates shown below the prompt box:

Product Mockups – Product shots and mockup presentations.
Social Post – Graphics sized and styled for social media feeds.
Promo Flyer – Promotional flyers and offer announcements.
Lifestyle – Lifestyle and in-context scene imagery.

Clicking a template pre-fills the prompt field with a ready-written prompt for that format. You can then tweak it to match your specific requirement before saving.

Step 6: Additional Settings (Optional)

Expand Additional Settings to fine-tune the output format and apply your brand assets.

Setting	Description
Size	The aspect ratio of the generated image – Square, Landscape, or Portrait. The exact pixel dimensions for each option are shown below the selector.
Background	Whether the generated image uses a transparent or opaque background. Defaults to Auto; you can also select Opaque. Transparent backgrounds are useful for logos, product cut-outs, and overlays.
Output Format	The file format of the generated image – PNG, JPEG, or WebP. Use PNG for transparency, JPEG for smaller photo files, and WebP for web-optimized delivery.
Design Kit	Applies a Design Kit style from your account to guide the generated image, keeping visuals consistent with your existing design system.
Brand Voice	Applies your Brand Voice details to guide the generated image, providing the AI with additional brand context.

Note: Design Kit and Brand Voice options pull from the assets already set up in your account. If you haven’t configured them yet, set them up first and they’ll become selectable here.

Step 7: Save the Action

Once your prompt and settings are configured, save the action. The generated image will be available as a variable in all downstream actions once the workflow executes.

How to Access the Generated Images

Once the action executes, the generated image is available in two places.

1. As Custom Values in Downstream Actions

In any action after the AI Image Generation step, open the custom value picker and navigate to AI Image Generation. Select the generated image to see three available values:

Image URL: The publicly accessible URL of the generated image. Opening this link displays the image directly, and you can download it from there. Use this value to attach the image to emails, send it over SMS/MMS, or pass it to an external system via web-hook.
Image File Path: The storage path of the generated image file.
Image File Name: The file name of the generated image.

2. In Media Storage

Every generated image is automatically saved to Media Storage. You can browse, download, and reuse these images from there at any time, just like any other uploaded asset – including in emails, funnels, websites, and social posts built outside the workflow.

Use Cases

1. Generating Product Mockups from Incoming Requests

Scenario: You want to produce quick product mockups or visual concepts to share with clients without waiting on a designer. Requests arrive from an external system – a Google Sheet, a form, or a partner platform – with a short description of what’s needed.

Setup:

Trigger: Inbound Webhook (carrying the product description)
Action 1: AI Image Generation – Product Mockups template, with the incoming description inserted into the prompt as a custom value. Apply your Design Kit for brand consistency.
Action 2: Send Email – Include the Image URL so the client receives the mockup immediately.

2. Personalized Campaign Visuals

Scenario: You want each contact in a campaign to receive a visual tailored to their interest, location, or purchase history – rather than one generic stock image for everyone.

Setup:

Trigger: Contact Tag Added (e.g., “campaign-enrolled”)
Action 1: AI Image Generation – Build the prompt using contact custom values so the image reflects that contact’s segment. Apply Brand Voice for tone consistency.
Action 2: Send Email or MMS – Use the Image URL as the campaign visual.

3. On-Demand Images from Conversations

Scenario: A customer interacting with your bot asks for a visual – a design concept, a room layout, a styled product shot. You want to generate and return it in the conversation without human involvement.

Setup:

Trigger: Customer Replied / Conversation AI handoff
Action 1: AI Image Generation – Use the customer’s message content as the prompt input.
Action 2: Send SMS/MMS – Return the Image URL to the customer in the same conversation thread.

More Ideas

Social content pipelines: Generate post graphics automatically whenever a new blog, offer, or announcement is published, so visuals keep pace with your content calendar.
Promo and event flyers: Produce flyers for recurring promotions, seasonal offers, or local events without a design request each time.
Catalog and listing visuals: Generate consistent lifestyle or white-background shots across a product range, useful where photography for every SKU isn’t practical.
Creative variations for testing: Produce several visual directions for the same campaign concept and test which performs best before committing to final production.
Blog and article imagery: Generate on-brand featured images as part of a content publishing workflow, replacing generic stock photography.

Tips for Better Results

Be specific in your prompt. Describe the subject, style, setting, lighting, and mood rather than just naming the object.
Use Enhance Prompt when starting from a short or rough description – it fills in detail the model needs.
Apply Design Kit and Brand Voice for anything customer-facing, so output stays on-brand rather than generic.
Match Size to the destination – Square for social feeds, Landscape for email headers and banners, Portrait for stories and mobile.
Test your prompt on a few sample contacts before publishing a workflow that runs at volume.
Save prompts that work well. Reusing a proven prompt structure gives more consistent results than rewriting each time.

Frequently Asked Questions

Q: Where is the generated image stored?

Every generated image is automatically saved to Media Storage and hosted at a publicly accessible URL. You can access it through the custom value picker in downstream actions or browse to it directly in Media Storage.

Q: Which model should I choose?

It depends on your use case. Models differ in visual style, photorealism, and how well they render text within images. If you’re unsure, run the same prompt through two models and compare the results before publishing the workflow.

Q: What does the Quality setting affect?

Quality controls the level of detail in the generated image. Auto (the default) lets the system choose an appropriate level for your prompt. High produces the most detailed output but takes longer to generate; Low is faster and lighter. Choose based on whether the image is customer-facing or an internal draft.

Q: Can I use dynamic data in the prompt?

Yes. The prompt field supports custom values, so you can insert contact fields, webhook payload data, or output from previous actions. This lets a single workflow generate a different image for every contact or every incoming request.

Q: What does Enhance Prompt do?

It uses AI to expand and refine your prompt, adding detail around style, composition, and lighting that you may not have specified. This typically produces noticeably better output. You can review and edit the enhanced prompt before saving the action.

Q: Do I have to use a template?

No. Templates are a starting point, not a requirement. You can write your own prompt from scratch, or apply a template and then edit the pre-filled prompt to match your exact requirement.

Q: How do I get a transparent background?

Open Additional Settings and set the Background option. The default is Auto; you can also select Opaque. For transparency to be preserved in the final file, choose PNG or WebP as the output format – JPEG does not support transparency.

Q: What are Design Kit and Brand Voice used for?

Both give the AI additional context so generated images align with your brand. Design Kit applies your visual style, while Brand Voice supplies your brand details. These options pull from the assets already configured in your account – if you haven’t set them up, configure them first and they’ll appear as selectable here.

Q: Can I send the generated image to an external system?

Yes. Because the image is hosted at a publicly accessible URL, you can pass the Image URL value to any downstream action – including outbound web-hooks to deliver it to an external platform.
