The Bing blog team have news....

Looking for that epic shot from last winter’s ski trip? Or the I-could-die-laughing photo of your roommate’s cat dancing? With more than 300 million photos uploaded to Facebook per day, photo viewing is one of the most popular things people do on Facebook. Bing now lets you quickly find that special photo (out of your friends’ thousands) on Facebook with the new Friends’ Photo feature. Now, with Bing, you can easily search and browse your friends’ photo collections--whether you’re looking for a specific moment, or just want to see what your friends have been up to at Friends' Photos.

Bing’s sidebar already shows you friends who have posted photos related to your search based on photo title, album description or caption, making it easy to find friends who might know about your search. Take for example, a search for Hawaii. With your friends’ likes and photos in sidebar, you can quickly see who to ask about the best accommodations or get great restaurant recommendations for your trip.
