How to Set Up AI Generate Image Feature

Customall provides an AI Generate Image feature that allows you to create fully personalized images directly from a text prompt. Instead of uploading a photo, you simply set up a prompt with variables like name, school, or year. When customers enter their own details on the storefront, the system automatically generates a unique image just for them.

This article will guide you through the process of adding, editing, and configuring an AI generate image layer.

1. Go to the Artwork Editor → Click the + icon → Select AI Generate Image.

2. Select AI Prompt

You can read this article to learn how to create a prompt with variables without an image input.

3. Configure the values for the layer settings, including:

• Variable fields: Each {{variable}} in the prompt becomes a field customers fill in. Fields sync automatically with the prompt - new variables are added and removed ones are dropped.

Variable fields include the following properties:

• Label
• Placeholder
• Help text
• Type: including:
• • Text
  • Number: only allows numeric input
  • Select: lets you create options for customers to choose from on the storefront

• Date: allows customers to select a date

• Image (1 photo): Uploads exactly one photo.

If a layer has 2 or more Image (1 photo) fields, you can show them as one upload box. The customer adds all photos in one place. Your prompt still uses each photo by its own name, like {{image1}} and {{image2}}. Turn on Group Image fields into one album upload.

Example: AI prompt: Portrait of {{image1}} , {{image2}} , {{image1}} , and {{image4}} in {{style}}

• Multiple image (album): Uploads a set of photos, between Min and Max photos.

Example: AI prompt: Portrait of {{photos}} in {{style}}

Photo limits

• 4 photos per layer. All photo fields on one layer share 4 photos. An Image field uses 1. An album uses its Max photos.
• File types: JPG, PNG and WEBP, up to 20 MB each.

Note: To change the display order of the variable fields on the storefront, you can drag and drop to rearrange the fields in the artwork editor.

• Test and preview: Enter sample values for the variables and click Test to see a preview.

• Button Text: includes:
• • Generate button text (e.g., "Generate Image")
  • Update button text (e.g., "Update Image")
  • Generate required error message (e.g., "Please generate your image before continuing")
  • Update required error message (e.g., "Please update your image before continuing")

• Output quantity: Resolution of the generated print file. 1 (1024px) is the fastest option and is great for apparel and previews. 2K (~2048px) and 4K (~4096px) produce sharper prints for canvas, posters, and large wall art. 2K and 4K resolutions require a configured API key. Please contact your team's admin if these options are unavailable.
• Image fit: allows images on the storefront to maintain their original aspect ratio. This ensures that images remain undistorted after Remove Background or Face Cutout is applied.
• Filter: includes face cutout, remove background, grayscale, mask
