Facebook introduced two more upgrades to its photo viewer.

First, the social network said the photo viewer will now display photos in the highest resolution possible, potentially making them four times larger than in the past.

Second, Facebook users now have the option to expand the photo viewer across their entire screen. Firefox and Chrome users can do so by clicking the arrows in the top right-hand corner of photos.
