Bing is expanding its Facebook integration to hopefully help users have a better photo experience across the site. Today, they are launching a new feature that allows Facebook users to browse and perform specific searches for all of their friends’ photos across the site.

Basically, it’s image search for your entire network of Facebook friends.

“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 www.bing.com/friendsphotos,” says Bing.

At Bing’s new Friends’ Photos search page, you can browse recent uploads from your Facebook friends or check out your own photos and albums. But the big draw here is the search function, which allows you to do a topic, name, or location search throughout your entire friend network. Let’s say I wanted to look at all of my friends’ photos involving beer:

I can also decide whether I want to filter for just my friends’ photos, pages’ photos, or any ans all photos.

Bing is also linking users to the Friends Photos feature via the sidebar, where Facebook-connected results are displayed during searches. As you probably remember, Bing’s sidebar was inserted into the results pages as a part of their significant redesign that brought three three-column format. Now, when you click on a photo that appears in the sidebar, you’ll be redirected to the Friends Photos search page where you can browse a collection of photos from that topic (for instance, a Hawaii vacation), or search for more photos from your Facebook pals.

Earlier this summer, Bing integrated Foursquare Tips into the social sidebar.
