So I turned this feature on and began moving my iPhoto libraries there as a whole. Seemed the easiest way to setup a sharing folder, even though it carries all of the iPhoto "extra" folders. I've got my iPhoto libraries ordered by years. The first year I moved over, by itself, worked fine. I could pull up the photos through the iOS app on the iPod Touch perfectly.

Then I added another, same thing.

But now I've got them all moved over and it doesn't seem to work. It can see the different folders and pulls the names down, but all I get are the blank icons (with replica of spinning star thing). But clicking on a photo (blank) icon brings up nothing but the empty icon. It knows how many folders there are and how many photos, but doesn't seem to be able to display them - except for the first couple of libraries I moved over. They still work fine. And they show up in iPhoto fine as well.
any help would be greatly appreciated.
