The Facebook/Microsoft alliance is bearing more fruit through a new feature that allows Bing users to scour Facebook photos. If you’ve ever had difficulty locating that one photo or album on Facebook, Bing’s “Friends’ Photos” beta is designed to do the legwork for you. The only thing that’s required to find specific photos is a keyword in the picture’s caption. Otherwise, you can search through your and your friends’ photos on a whim, though only ones that are made viewable, Microsoft said. The feature is live now, so give it a shot and try searching through your Euro trip 2011 photos through Bing.
