Description Settings
Main Image – an image that the potential buyers will see on your eBay Item page and next to the Item title in search results.
Default Image Url – allows specifying the absolute URL to the default Item image, e.g. http://mymagentostore.com/images/defaultimage.jpg. If the Main Image is not provided for the Item, this image will be used instead. This will help to comply with eBay requirements.

Gallery Images – allows adding up to 11 extra photos for each Item. The gallery images will be displayed as the small thumbnails under the Base Image on the eBay Item page.
Change Images for Attributes (only for Configurable Products) – allows selecting the option by which the Item images should be switched on eBay.
Variation Attribute Images (only for Configurable and Grouped Products)- allows adding up to 12 images for each variation of Variational Item.
