Well, look at what we have here. It appears Facebook has either begun testing or begun rolling out a new interface for pictures on the social network, one that puts a heavy focus on "Sponsored" advertisements and comments. The new UI will place the photo behind a dark background and hovering over the left side of the window will fade in the "Like" button and other tools if you're the owner of the picture.
