For example, John Smith logs into this site using his Facebook username and password and he submits a translation of a paragraph. This site records the translation as submitted by someone with the unique Facebook id of 123456789. The translation history of this paragraph will show a small profile picture of John that points to <img src='http://graph.facebook.com/123456789/picture'>. If John sets his Facebook privacy settings to only allow his friends to see his profile picture and no one else, then when a friend logs into the site, this code will make his real-time profile picture appear. All others will see a profile picture as handled by Facebook. Names are similarly handled.
