Viewing the scans in alphabetical order by file name is what I had in mind. For some reason, iPad doesn't sequence that way. It uses some date associated with the file on the PC. I've about decided I'm going to have to use a 3rd party APP for the iPad. If you have found a way to do it alphabetically using the Photo viewer, I'd like to hear more.
I haven't signed up for Mobile Me yet. I hadn't seen any reason to do so, but maybe that's the answer?
