I have been using an Eye-Fi SD card in our digital point-and-shoot camera for a week now. I’ve been very impressed so far. As described by the vendor:
The Eye-Fi Card is a wireless memory card. It automatically uploads pictures from your digital camera to your PC or Mac and to your favorite photo sharing, printing, blogging or social networking site.
No cables, no waiting, no hassles.
It functions as described and with no trouble photos are automatically uploaded to our computer and photo site (snapfish).
