I thinking checking MIME type is better. But as another monk pointed out, you might want to check the returned file size to make sure it's not a generic image representing error. One could minimize the possibility of accidentally deleting non-error images of the same size by storing the names of the suspicious images and delete them once two or more of them were found in the same directory.
