How to send data like pictures between two computuers using two xbees

How to send data like pictures between two computuers using two xbees? I've seen tutorials that use the xctu software to send text between two computers, but is it possible to send pictures or other data of any kind? If so how?

but is it possible to send pictures or other data of any kind?

XBees send data. Whether that data represents a character that you can recognize or a byte of picture, music, or movie data matters not at all.

I know, but how do you do it? What software to use, a tutorial, anything.
