I fired up Apple's iPhoto Uploader for Facebook, and I hadn't done so before so had to connect the app with my Facebook account. To do so you have to give permission to the app to do a variety of things (see photo), maybe. Although presented here in a nice visual list, this seems to be the standard list of things you have to give every app in Facebook when you want to use it (so I use practically no apps).
