is there any way to get pictures on an ipod nano besides itunes?

Answer 1

No, there isn't. Sorry. Unless you don't want to view them.

If you only want to transport them, and not view them on your iPod, you can allow disk usage. Once you allow disk usage, you can plug your iPod into any computer and use it like a flash drive to transport photos (see http://www.apple.com/support/ipod101/maximize/2/#4 for information on enabling disk usage)

Hope this helps.
