Hi Peter, if you are having this issue in a hosted environment, you may want to add some logging to the Product.aspx.cs class, specifically within the: LoadProductImages() and DisplayImage() methods. Just add a Try-Catch in both of these methods and log the errors with the
MettleSystems.dashCommerce.Core.Logger class
This will help you get some more information as to why your images are not showing up within the Product Detail page. If you get more information about the problem I'll be able to help you more.
