I am trying to use Dropsync to synchronise the photos in my 100ANDRO folder to a file on my PC. It works fine BUT the Android Camera Gallery seems to show some photos that are not in the 100ANDRO folder, and ignores some that are in there.

Does anybody know how Android decides which photos to show in the Camera Gallery, and how to configure it to show only all the photos in the 100ANDRO folder?
