You can view your MobileMe Gallery and quickly access your friends’ galleries with the Gallery app for iPhone and iPod touch. For help using the Gallery app, open the app, tap Settings in the upper-left corner, and then tap Gallery Help.

When you arrange your albums at me.com/gallery, you may notice that they are randomly rearranged after you log out and then log in to MobileMe.

Also, when you upload multiple photos or movies to an album at me.com (either at gallery.me.com/membername or me.com/gallery), they are posted in a random order.
