One thing I've wondered was that Facebook began showing the recent photos you'd taken at the top of the app, and prompted you to share them. Are they sending every photo you take to their servers to feed it back to you at the top of your stream? I realize they could implement this feature by displaying local photos without sending them to their servers, but I've never seen confirmation that photos remain on your device only until you post. I uninstalled the app awhile back, so maybe they don't do this anymore, but anybody have any insights into how they handle your photos?
