I am new to ipad. I have uploaded photos via itunes. I have them in folders. It now appears if I want to add photos to a particular folder I must re-sync the entire group of folders or else they will all dissapear except for the folder where the photo was added. Seems cumbersome with a thousand photos. Same problem to delete one photo from ipad. It appears that the only way this can be done is to delete the photo on the computer and re-sync the remaining 1000 photos.
I must be missing something--- at least I hope so.
