When Apple brings out the iCamera, it will work...
For now, there is no feature like this for the iPod.
PS. Do you remember Apple's foray into cameras?
I have a 20 gig I Pod and I was wondering if I bought a compact flash reader if I could save the pictures on the I Pod. This would beat spending $200 dollars on four 256 compact flash cards. If anyone thinks this would work let me know.
