Microsoft Advertising has introduced multi-image ads for Shopping campaigns, now appearing in Bing search results, enhancing the ecommerce advertising experience.
This new feature enables advertisers to showcase multiple product images within a single ad, giving shoppers a richer view of product details directly on Bing before clicking through to a retailer’s site.

The update is particularly relevant for improving engagement and driving intent. By presenting several product visuals, brands can better display product features and encourage potential customers to interact with ads in new ways.
Additional images are added in the product feed using the optional additional_image_link attribute. You can include up to 10 images, separated by a comma delimiter.
