When I was backing up my files, somehow I lost all my pics and video after Set. 2012. Any idea where they could be or where I should go looking? They didn't go into the trash. Its about 600 pics. Also, in iphoto, after retrieving what files I could from my backup, all I see are frames where the pictures should be. If I scroll through the pics I see the pic very briefly but then the frame comes back. How do I get my pics to show. I think I really screwed up this back up thing!! Thanks for any help.
