Eye-Fi wireless SD card
These brilliant 2gb SD cards contain fully independent wirelesssoftware and hardware that will automatically upload pictures to thephoto sharing website of your choice (or even to your home computer)via any locally available wireless network. No actual modifications aremade to your images during this process (unless you want them resized),and the whole thing is managed at the Eye-Fi website. So, just toclarify, all your digital camera has to be capable of is saving imagesto a standard SD card, and the Eye-Fi card will work for you. As youmight expect, range is not great (well under 100 feet), but powerrequirements (although unspecified) are supposed to be minimal.
