Facebook is rolling out shared photo albums, as first reported by Mashable. Users can share access to an album with up to 50 contributors, who can each add up to 200 photos.
For those of you who aren't math whizzes, that means shared albums can be as large as 10,000 photos. Previously, albums were limited to 1,000 total photos and users could only add pictures to their own albums.
This new feature should be good for user engagement in groups of friends and with larger albums. Facebook has done a good job of focusing its browser-based photo section around albums and larger batches of photos, while leaving (Facebook-owned) Instagram to dominate single photos. Users can beautify and share quick snaps in time with their friends via Instagram, but for larger life events (weddings, graduations, even just cool vacations), they can share much larger batches of photos on Facebook.
