Facebook is currently rolling out a new photo viewer which functions a lot like lightboxes. Once you select a photo from any album the viewer pops up. Other than giving you a bigger photo, the viewer also allows you to tag, rotate, add captions, and comments. There’s also an ad on the lower right hand corner. You can shuffle through the album by clicking the next/previous buttons.
Awesome work Facebook. 
Ayuz! Lupet ng Facebook… More Fun for everyone!
