I enjoy looking at my photos on the iPad 2, and have been downloading them from the various photo sites I use and using an app. to put them in topic- or subject- related folders. Two photos I downloaded do not show up in the normal Apple "Photos" folder but they show up as blank squares labeled JPEG in the app. view of the Photos folder. How do I delete these? The app. will not import them to the screen from which I could delete them, and the normal Photo folder won't show them at all... I think there must be a problem with the files on the photo site, although they display normally using a browser to view the site.
