Facebook updates photo viewer with hi-res images and full-screen mode

No more than 24 hours after introducing you to Acquaintances, Facebook is rolling out a couple of new features for its photo viewer. The social network's fresh bits will let you get a resolutionary look at all those images shared by your friends, boosting the max resolution size to a whopping 2048 x 2048 -- perhaps to pair up nicely with a certain Cupertino-born slate. Additionally, now you'll be able to check out those hi-res photos in full-screen mode, though you'll need to be on the most recent version of Firefox or Chrome to do so (sorry, Safari). Best of all, there's some extra Face-uh-oh-book goodies waiting for you after the break.
