The Eye-Fi card is famous for being a cool, fun way to upload, inadvertently, images of you and your friends naked or on the toilet. Now, however, you can upload those naked photos to your local FTP/FTPS server. This service allows you to bypass standard photo-sharing sites like Flickr and dump your stuff up unfettered by the limitations placed upon us by photo sites.
Here are the instructions. Happy uploading and be sure to make those images public!
This also, admittedly, allows you to run your own photo sharing service and to keep your photos completely private.
Something special for memory cards. No need to connect by wire to PC to transfer those photos.
