I have discovered, and used, a really useful app! My iPod was replaced yesterday, and in the process I lost the photos (which are also on my iPad) from it. Couldn't fathom out how to send them over - tried e mailing but very laborious. So I googled, and came up with this app. If you look up "photo transfer" in the apps store this will come up. It works like a dream, using your wiFi network and only that, so it's secure.
You have to install it on your devices, but of course only pay for it once. It also works with your PC, even if it's windows, though I haven't tried that yet.
