Eye-Fi updates its software to allow secure and unsecured FTP transfers: It's funny how long it can take to get the basics in place, but Eye-Fi has finally added a feature that should make many digital photographers happy. Eye-Fi's digital media cards that sport an internal Wi-Fi radio can now transfer images via unsecured FTP and FTP over SSL/TLS. A card with the Online Sharing option is required; that option can be separately activated on some cards, and is included with other models.
FTP is an ancient and extremely common method of file transfer, requiring very little fuss to move data around. Early Wi-Fi support in expensive pro cameras relied on FTP because there wasn't any other reasonable mechanism to move files around. It's taken a few years to get back to the same point.
FTP lacks intrinsic security, but can have security options layered on top. FTP over SSL/TLS relies on a secured tunnel being created--precisely like a tunnel used for a secure Web session--after which FTP can flow without anyone between the two end points being able to sniff FTP passwords or data.
Some people use FTP as the basis of automation operations. You set a watch file that's accessible via FTP, and as images are loaded into that file, actions are performed on images, such as auto-correcting and resizing, or adding to an online gallery.
