How Product Images Show Up in ChatGPT Shopping and Google AI Overviews

Key takeaways

• Both surfaces build on product data you already control. ChatGPT reads merchant feeds, crawled product pages, and third-party providers. Google's AI Mode and AI Overviews draw on its Shopping Graph, which is fed by Merchant Center and product structured data.

• Google sets the specs, OpenAI mostly doesn't. Merchant Center asks for one clean main image, up to 10 additional images, and up to five lifestyle images, with a 500 x 500 pixel minimum from January 31, 2027. OpenAI's feed asks only for a direct, public image URL.

• There's no special markup for AI answers. Google says AI Overviews and AI Mode have no extra requirements beyond normal product data, and OpenAI's feed uses ordinary image fields.

• Crawlers decide who's eligible. Blocking OAI-SearchBot keeps your pages out of ChatGPT search answers, and Merchant Center needs Googlebot and Googlebot-Image to reach your images.

• AI-generated images need their metadata. Google requires product images made with generative AI to keep an IPTC tag saying so. OpenAI's feed spec doesn't address AI images.

Where AI shopping answers get product images

Neither OpenAI nor Google publishes how it picks the exact image a shopper sees. What both do publish is where their product data comes from, and that's what you can control.

ChatGPT has three documented sources:

• Merchant product feeds. OpenAI's Agentic Commerce Protocol feed gives ChatGPT "titles, descriptions, images, price, and availability." Direct feed access is open to approved partners, and new merchants join a waitlist at chatgpt.com/merchants. Merchants on some large commerce platforms are already connected through those platforms and don't need to apply.

• Crawled product pages. OpenAI's merchant FAQ says a feed isn't required if ChatGPT already crawls your site, though feeds give "greater control over how your products appear." Shopping research, launched in November 2025, looks across the web for "price, availability, reviews, specs, and images," reading product pages directly.

• Third-party providers. ChatGPT also uses "structured metadata from first-party and third-party providers," according to its help center.

Google feeds AI Mode and AI Overviews from its Shopping Graph, which held more than 50 billion product listings in May 2025, with more than 2 billion refreshed every hour. Merchants get into it two ways: a Merchant Center feed and Product structured data on their pages. Google's product structured data guide says providing both "maximizes your eligibility to experiences and helps Google correctly understand and verify your data."

How ChatGPT shows products

When a question has shopping intent, ChatGPT shows "product options with imagery, product details, and links to sites." A product appears in the carousel "when ChatGPT perceives it to be relevant to your intent," based on the query and context such as memory.

A redesign on March 24, 2026 made results "more visually rich," let shoppers browse products in the chat, upload an image to find similar items, and compare products side by side on price, reviews, and features. Since October 1, 2026, clothing and accessory listings carry a "Try on" button that generates a try-on image from the shopper's selfie.

A few details are worth knowing before you see your products there:

• ChatGPT may add its own labels to product images, such as "Budget-friendly" or "Most popular." OpenAI says these are generated by the model and aren't verified statements.

• It may rewrite your product title and description into a simpler version.

• Product results aren't ads. OpenAI says they're "selected independently by ChatGPT," and ChatGPT's ads are a separate product.

• Most purchases happen on your own site. OpenAI launched Instant Checkout in September 2025, but said in March 2026 that it's letting merchants use their own checkout while it focuses on product discovery.

OpenAI doesn't say which image appears in the carousel, comparison view, or try-on, whether additional images are shown, or how images are cropped.

How Google AI Mode and AI Overviews show products

AI Mode shows shopping results as images. For a visual question it returns a browsable panel of images and product listings, and since November 2025 shopping answers bring together "rich visuals" with price, reviews, and inventory. Shoppers can also start from a photo they upload. AI Overviews link to product pages and listings the same way.

Google states plainly in its guide to AI features that "there are no additional requirements to appear in AI Overviews or AI Mode, nor other special optimizations necessary," and that there's "no special schema.org structured data that you need to add." The images Google already has from your feed and pages are the ones these surfaces can use.

Two Google behaviors affect how your image looks:

• Cropping. Merchant Center warns that Google "may test subtle cropping on your image to better frame the item and highlight key product details."

• Lifestyle images are limited to some surfaces. The lifestyle_image_link attribute is "only available for browsy surfaces," and Google doesn't say whether AI Mode panels count.

Image specs side by side

OpenAI's spec does set a few rules: image URLs must be "publicly accessible," HTTPS is preferred, each variant gets its own row and image, and the color field should be "consistent with the product image." Its original September 2025 spec also had video and 3D model fields, and both have since been dropped.

Google's main image rules go further. The product should fill 75% to 90% of the frame, every variant needs its own image, and promotional overlays, watermarks, added logos, borders, and placeholder images aren't allowed. Merchant Center no longer names a background color for the main image, but Google's merchant listing structured data guide still says pictures "against a white background" are preferred, so a plain white or light background remains the safe choice.

Getting eligible in ChatGPT

1. Allow OAI-SearchBot. OpenAI's crawler documentation says sites that opt out of OAI-SearchBot "will not be shown in ChatGPT search answers." Robots.txt changes take about 24 hours. Blocking GPTBot, OpenAI's training crawler, doesn't affect search.

2. Check your firewall and CDN as well as robots.txt. Bot managers can block OpenAI's crawlers even when robots.txt allows them. OpenAI publishes its crawler IP ranges for allowlisting.

3. Check whether your commerce platform is already connected. Some large platforms pass catalog data to ChatGPT for their merchants.

4. Apply for a direct feed if you need more control. The feed has nine required fields, including image_url. OpenAI recommends starting with a sample of about 100 items and then sending a full snapshot at least daily.

5. Make every image URL public and direct. A link to a page, a login-gated asset, or a URL that expires won't work.

Getting eligible in Google

1. Keep product pages indexable. A page must be indexed and eligible for a snippet in Google Search to appear as a supporting link in AI Overviews or AI Mode.

2. Submit products in Merchant Center. Free listings put products across Google Search and other Google surfaces.

3. Add Product structured data with an image property that points to crawlable, indexable images, ideally several at 16x9, 4x3, and 1x1.

4. Allow Googlebot, Googlebot-Image, and Storebot-Google. Merchant Center needs the first two to fetch images, and Storebot-Google covers Google Shopping surfaces. Blocking Google-Extended doesn't affect inclusion in Search or AI Overviews.

5. Watch the reports. AI Overviews and AI Mode traffic appears in Search Console under the Web search type, and Merchant Center's AI performance insights, announced in May 2026, are rolling out by country.

AI-generated product images

Google's AI-generated image rule is specific: "All images created using generative AI must contain meta data indicating that the image was AI-generated," using the IPTC DigitalSourceType tag. It applies to main, additional, and lifestyle images, and Google tells merchants not to strip the tag. Image compression and CDN optimization can remove metadata, so check the image at its live URL as well as the file you exported. Merchant Center also lets you add a visible AI label, which doesn't count as a prohibited overlay.

OpenAI's feed documentation doesn't mention AI-generated images. Other channels set their own rules: Amazon asks sellers to tag images with photorealistic AI people, as covered in our Amazon product image guide.

A product image checklist for AI shopping

1. Use a main image with the product alone on a plain, ideally white, background, with no text, badges, or borders.

2. Fill 75% to 90% of the frame with the product.

3. Export at 1500 x 1500 pixels or more, and never below 500 x 500.

4. Save as JPEG or PNG, which both platforms accept, under 16MB.

5. Give every variant its own image, and keep the color field matched to the photo.

6. Add additional angles, up to 10 for Google, through additional_image_link and additional_image_urls.

7. Add up to five lifestyle images for Google through lifestyle_image_link, each at least 600 x 600, with no padding to fix the aspect ratio.

8. Mark up every product page with Product structured data and several image sizes.

9. Write descriptive alt text and file names, and use <img> tags, since Google doesn't index CSS background images.

10. Use stable image URLs, and change the URL when the image changes. Google crawls a new URL within three days but may take up to six weeks to notice a changed image at an old URL.

11. Allow OAI-SearchBot, Googlebot, Googlebot-Image, and Storebot-Google in robots.txt and in your CDN or bot manager.

12. Keep the IPTC AI metadata on any AI-generated or AI-edited image.

13. Refresh feeds at least daily so images, prices, and stock match the page.

Frequently asked questions

Does ChatGPT use my Google Merchant Center feed?

OpenAI doesn't say it does. Its documentation names its own product feed, commerce platform integrations, crawled pages, and third-party data providers as sources, so plan for ChatGPT separately.

What image size does ChatGPT need?

OpenAI doesn't publish one. Its feed asks for a direct, publicly accessible image URL, with JPEG and PNG given as examples. Meeting Google's specs, at least 500 x 500 and ideally 1500 x 1500 pixels, covers both.

Is there special markup to get product images into AI Overviews?

No. Google says AI Overviews and AI Mode need no special structured data or optimization. Standard Product markup and a Merchant Center feed are what feed these surfaces.

Do I need a white background for AI shopping results?

It's the safest choice. Merchant Center asks for a clean, unobstructed view of the product without naming a color, and Google's structured data guide says white backgrounds are preferred.

Can I use AI-generated product images?

Google allows them if the IPTC DigitalSourceType metadata stays on the file. OpenAI's feed documentation doesn't address them. Either way, the image has to show the real product accurately.

Will blocking GPTBot hide my products from ChatGPT?

No. GPTBot collects training data. OAI-SearchBot controls whether your pages can appear in ChatGPT search answers, and blocking it is what keeps you out.

Can shoppers buy inside ChatGPT?

Mostly not. OpenAI said in March 2026 that it's moving away from a standalone Instant Checkout, so most purchases that start in ChatGPT finish on the merchant's own site or app.
