Additional Image URLs [additional_image_urls] Field for Product Feeds

Optional but Recommended for Rich Product Representation in ChatGPT

The additional_image_urls field allows you to provide extra images of a product, in addition to the main image.

These images help ChatGPT:

• better understand product appearance,
• visualize variants, angles, or details,
• improve confidence when comparing similar products.

This field replaces the legacy additional_image_link attribute.
Only the new name is supported.

When to use

Use this field when your product benefits from multiple visuals, such as:

• different angles,
• close-ups,
• lifestyle shots,
• variant examples (color, texture, finish).

Providing multiple images improves how AI systems interpret and present the product.

Format

• Type: String
• Format: Comma-separated list of URLs
• Accepted protocol: https (recommended)
• Repeated field: No
• Maximum count: Up to 10 images

Example:

Each URL should point directly to an image file (JPG, PNG, WEBP).

Relationship with legacy field

If your feed still uses additional_image_link, the images will not be read by ChatGPT.

Minimum requirements

• Use a comma-separated list of valid image URLs.
• Ensure each URL resolves correctly (HTTP 200).
• Use clear, product-relevant images only.
• Do not include spaces inside URLs.
• Do not use non-image URLs or landing pages.

SEO / AI Tip

While image_url defines the primary product image, additional_image_urls provides visual context.
Products with multiple high-quality images are easier for ChatGPT to compare, explain, and recommend.

Missing or invalid image URLs may silently reduce product visibility.
