What do I need to know about custom product images?
Customizable backgrounds: Sponsored Display’s default creative automatically uses product imagery from an advertised ASIN’s detail page and supports a white background. Custom product images allow you to upload your own graphics, including those with bespoke background colors and art direction, to help convey your brand and product story.
One image for all creative sizes: When using a custom image, your ad can still serve in up to 12,000 different size variations wherever they spend time. You only need to upload one rectangular image, which you can also crop into a second square image.
Reuse across sponsored ads: You may apply the custom image you used for other sponsored ads programs to the Sponsored Display custom image creatives and vice versa. Note that the image will still be reviewed against moderation policies for Sponsored Display.
Availability: This custom image creative feature is available in CA, DE, ES, FR, IT, IN, JP, UAE, UK, and US.
