Facebook has introduced 3 new features for Photos. These include high resolution images (storing bigger pictures), a new viewer for browsing photos, and a new uploader with better tagging. 

Facebook is rolling out support for print-quality, hi-res photos. They’re increasing the size of the photos stored from 720 pixels to 2048 pixels on the largest side or 8 times bigger overall. 

"The new viewer makes it simpler and faster to navigate photos," says Facebook’s Sam Odio. "You can now view photos and even whole albums without even having to go to a new page. Instead, the photo opens in the center of your screen, and you close it when you’re done. There’s no need to go back and forth between pages or reload the page."

"A new light box (the dark frame around your pictures) makes viewing photos a richer experience," adds Odio. "We also rewrote all the code for the viewer from scratch, so paging through photos will be noticeably faster."

The new uploader uses Flash to give users what Facebook says is a better experience, particularly when you’re uploading a lot of pictures. The new uploader also lets you tag multiple photos in the same album at the same time, as well as tag photos of the same person with less effort.
