All of the images for your products are hosted in SellerCloud.
Importing your product images will store them on the server, so they are always available for publishing to your channels.
The URL of an imported image appears on the Image Hosting Options page shown here (Company > Toolbox > Images Hosting Option):
In order to produce a valid image URL, the URL shown on this page must exactly match the URL of your SellerCloud account. For example, if your SellerCloud URL is https://tt.cwa.sellercloud.com, this same image URL must appear here.
Before you post any item or image information to a channel, ensure that this URL is an exact match; otherwise, the channel may respond that no image was received.
