Bill's daughter is on Facebook and has a ton of pictures stored there. How can she back them up? Leo says that she can upload every picture she takes to a private album in facebook. Then she can download them. They'll be pretty compressed, however. Google Chrome has an extension called Download DB Album mod, which will "scrape" her Facebook feed and download them all.
A better choice is to save the originals on Flickr, Google Plus and One Drive. She can set her apps to automatically back up her photos, too. Facebook is probably the worst possible option for backing up photos.
