I've optimized my photos so they won't take up too much space on my iPhone. I have 94 photos that only take up 6 mb total. But when I look in iTunes it says my photos are taking up 60 mb! When looking in my picture dir on my PC (XP) the iPod Photo Cache dir has 50 directories in it (F00 - F50) each about 1 mb. That's 50 mb of .ithmb files! Why do I have so many F** directories? Do I need all of them? and why are they so large when compared to my actual photos?
