I have just had a successful experiment with the free version of this iOS software for transferring picture files from one device to another: Bluetooth Photo Share. I needed to transfer some pictures from Cindy's iPad 2 to my iPod 2, and this worked well enough.
Bluetooth isn't terribly fast, so moving dozens of image files (one at a time) might seem somewhat tedious; moving this handful-or-so didn't take too long.
Needs no Network, just that the two devices are in the same room, both running this app.
