At a recent family event I wanted to do a slideshow on my iPad 2 of some photos I had taken. I did the slideshow and found out that I now had doubles of every photo I had installed in albums. Photos that were saved off the web were not doubled. When I looked in my iTunes media folder I have single images. My question is how do I delete the extra copies off of the iPad? I do use mine as an electronic portfolio and hope to resolve this soon.
