Now that is a good idea

I came across this researching something else, but who is this for a snazzy idea, putting a wi-fi transmitter into a camera's  SD memory card. It is called an Eye-Fi. There is a bit of set up required on your PC or Mac to configure it, but after that you can upload your photos from the camera wirelessly, and in can be automatically setup to also upload your photo to your favourite website, like flickr, photobucket, even facebook. At present they don't work with public wi-fi hot spots (they can't log in by themselves). And yes the camera battery will be used when the card is transmitting. The other bad news is the Eye-Fi is only supported in USA (but hopefully that will change)
