How to create and use AI generated images

Generate, preview, review, and approve AI product images with a Gemini or OpenAI connection.

Who can use this feature

You need the Core Pro plan in your Channable subscription to use this feature.

Before you start

You'll need

• A Core Pro plan in your Channable subscription.
• An image-type project field containing the source images.
• A Gemini or OpenAI connection, or an available Trial connection.

Trial connection

Use the Trial connection to test image generation.

• The Trial option uses Channable's own Gemini connection. You don't pay for this.
• You can generate up to 5 images with the Trial connection. Once you've generated 5 images, you'll need to connect to Gemini or OpenAI to generate more.
• After you connect Gemini or OpenAI, the trial connection is unavailable.

Good to know

• The generator uses a source image. It cannot create a product image without one.
• Generated images do not appear in the output field until you approve them.

  • When you approve an image, it is saved to the output field you select in step 1.5. Choose an empty field to keep the source image. Choose the source field to replace the source image.
• Read AI generation usage and costs to understand token usage, pricing, and data handling.
• Channable uses Gemini Gemini-3.1-flash-image and OpenAI gpt-image-2.5 Sunburst.

1

Begin the setup

1. In your project, go to Generate with AI.
2. Click Generate with AI.
3. From the content type options, select Images.
4. Click Continue.

2

Set the source image and output field

1. In the Name field, enter a descriptive name.
2. At AI connection, select Trial, Gemini, or OpenAI.
3. If you select Gemini or OpenAI, select an existing connection or create a new Gemini or OpenAI connection.

How to choose an AI connection for images

• Gemini is twice as expensive as OpenAI.
• Gemini is typically slightly faster and more accurate than OpenAI, but the difference is minimal.

1. At Image to use, select the image-type field containing your source image, such as image_link.

No source image field?

This error typically happens because the field has not been set correctly to the Image type.

To fix this, In Project fields, locate the field and set its type to Image. Return to the generator and select it.

1. At Field to save the optimized image, choose where to save approved images:

   • Select the source image field to replace the source image.
   • Create a new image-type field in the flow, such as image_ai, and select it to keep the source image.
2. Click Save and continue.

Filter items for image generation

Tip

Start with one product category and refine the prompt for that category. Create separate prompts for other categories instead of using one prompt for all items.

1. In Select items, set the filter for products that need generated images.
2. To select every item, leave the condition as If all.
3. To select a group, replace all with a project field and enter a condition. For example, set If title contains dress.

   
4. Click Apply to update the selected items.
5. Click Save and continue.

Important

Review the selected items before generating images. Items without a source image cannot produce a useful product-based result, and will return an Input image not found error.

4

Create and review image previews

1. In Prompting, review the example prompt and describe the image you want to create.
2. At Image ratio, select the ratio that suits your destination.
3. Check the estimated preview cost.

   
4. Click Generate previews.
5. Review each preview and refine the prompt if needed.

Click Compare to original to view the source and generated images together. Click Large preview to inspect an image more closely. When multiple previews are available, click Next to review each item.

Important

Each new preview generation adds a cost.

5

Generate images from approved previews

1. Check the estimated generation cost. If you’re using the Trial connection, you can generate up to 5 images for free.
2. Click Generate images.
3. Wait for the images to finish generating.

Use the Generate images menu to generate more images or regenerate the selection.

6

Duplicate source images

Channable groups products that use the same source image. It generates one image for each unique source image.

The number of generated images can be lower than the number of items selected. When one generated image applies to multiple products, their IDs appear below the image.

Approve or regenerate each image

We recommend reviewing images one at a time:

1. In Review, open an image to compare it with the original.
2. Click Approve to save it to the selected field, or click Regenerate to create another version.
3. Click Next to review the following image.

To work faster, hover over a thumbnail and select Approve or Regenerate. Use Approve all or Unapprove all to manage images in bulk.

7

[Optional] Automatically generate images for new matching items

1. In Review, click Automation.
2. Turn on Generate content for new items to generate images for new items matching your filters.

Important

Automation only works for active projects.

1. If you have tested the results, turn on Approve new content automatically.
2. At Daily generation limit, enter the maximum images to generate each day.
3. Save the automation settings.

Important

Set a daily limit before enabling automation. This controls generation costs when many items are added.

8

Map approved images to your channel

1. In your feed, open the mapping step for the destination image attribute.
2. Map the field containing your approved generated images.
3. Save and run the feed.

The channel receives only images that you approved, unless automatic approval is enabled.

Troubleshooting

Channable cannot download the source image

Check that the source image URL is publicly accessible and returns a supported image file. Then generate the preview again.
