Bing's social search integration with Facebook just got deeper. You can now search your Facebook photos and those of your Facebook friends after authorizing the Bing app.

When you use the Microsoft search engine to search photos, you'll see the results arranged in the now-ubiquitous Pinterest-style waterfall layout, as shown above.
The new Bing search feature also introduces something you can't even do on Facebook itself: Search for specific keywords in photo captions or album titles. For example, if I search for "Italy" on Facebook, there's no way to find my friends' photos with related captions. But on Bing search, I can see all the photos of my friends in Italy.

"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 wrote in a blog post. "Bing now lets you quickly find that special photo (out of your friends’ thousands) on Facebook with the new Friends’ Photo feature."
However, the improved ability to find Facebook photos may not be something people want. Many users complained when Facebook Timeline made it easier to search users' pasts in photos.
If you're worried about your photos from Spring Break 2007 showing up in search results of the masses, rest assured. Only your friends who already had access to the photos can see your uploads.
"In Bing Friends’ Photos, your friends will only see photos you've shared with them, and your photos can't be seen by anyone other than your friends on Facebook," the blog post states. "Microsoft is committed to being clear about how we use your data, and to giving you control, enhanced security, and benefit for sharing your data."
The Friends' Photo feature has a second tab that lets you see only your own photos, which could be helpful if you're trying to locate a photo several years back on your Timeline.
Bing's most recent social search integration came last week, with the addition of Quora.
What do you think of this integration? Let us know if you find it to be a welcome addition to the Bing-Facebook features -- or if you'd rather it not be easier for people to dig up the skeletons in your Facebook photo closet.
