I just helped my client set up her new iPad and her new Mac. Moved thousands of pictures over from the old PC and they look fine on the computer. When i sync to the iPad, though, many of the pictures come out corrupted, where you'll see half, a third or whatever, of the picture, and the rest is just white. I've tried deleting the iPod photo cache and re-syncing, but the problem remains. Interestingly, when i told it to do just a very small set of pictures, that set was fine. But when i did a larger group that included that smaller group, many of the pictures were corrupted including some of the small group that looked fine when they were the only pictures synced. Any suggestions? Edit: after trying everything else I could think of, i switched her photo library from syncing from folders (as she used Picasa) to syncing from iPhoto, which worked. Hope this helps someone else!
