I have products that have an attribute for an external image location. When one of these products is added to the cart, I would like the cart thumbnail to to be replaced by this external image file.
Because I'm making this as part of an extension, for compatibly/portability reasons I really do not want to edit
I would rather just make it so when
is called it knows to look for the external URL first, and display that if it's there.
I wanted to override
but then resize doesn't work properly.
Any ideas or help implementing this would be awesome. I know there must be some way to do it because there are extensions that allow all images to be moved to S3. Essentially it's the same idea. I think.
