I have the Shopp plugin and have been having trouble with it. I contacted them and they were very helpful, but I am still having the problem. They told me that something was inserting a code on my image files and creating a broken link. If I uninstall wordpress and reinstall it everything works fine for a while then back to the same no images. Anyone else have issues like this or know of a possible solution? The theme doesn’t seem to matter and it even happened with all other plugins deactivated.
