This is not user error. I select the whole folder in the iTunes sync page yet only some of the photos are showing up on the iPad. I assume it has something to do with the extension of the photo but I'm not sure. Some.jpg and.png photos show up but others don't. All of the photos show up on the iPhotos applicaiton on my iMac though.
