When you create a product detail page, you have the option of adding one main image and up to eight additional images to your page. You can do this when you first create the page, or you can edit the page later. You can also contribute images to pages you have not created. Learn more about Editing Product Pages.
Images are intended to represent the general characteristics of the product, and not your particular copy. It is not appropriate to use copyrighted images of other individuals or companies for a product detail page.
