Digital Picture Frame: Any that can hook up USB, so we can email photos?

[tenders]

I have the Kodak wifi frame and it has 128MB internal memory, a multiformat card reader, and a USB port in addition to the wifi capability.

When you plug the frame into the computer, two drives show up in the Finder: the internal memory, and whatever is plugged into the card reader.

I don't know if all frames work this way.
