Using all latest commerce/cms nuget packages/modules.
Open product details in CMS->Commerce->Catalog and find out "broken" image link at top left corner of the "all properties" view:
http://localhost:1113/globalassets/img_27122013_133849.png/LargeThumbnail?time=1395832439552 that returns 404 code.
Is it a bug, or problem on my side?
Did you update your Image content type file to inherit from CommerceImage instead of ImageData. It's a requirement to get the LargeThumbnail to work.
No, I didn't:)
