At long last GIFs have been integrated into Facebook! You can now post and view them using both the desktop and mobile sites, as well as the application. At the moment you can only add them if they are hosted elsewhere on the internet first, by copying and pasting the links into a status or comment box. If you try to upload directly from your computer you will find they become nothing more than a frozen image at the moment. Obviously with GIFs being a new addition to Facebook, things may change regarding the direct uploads.
Of course this update can only mean one thing though, right? Prepare for never ending unrelated GIFs in the Facebook comments! I must admit, i have often had a good laugh at what some people manage to find! What's your favourite GIF?
