Yahoo! Integrates Images from Facebook Profiles in Search Results
Yahoo! is now displaying pictures from Facebook profiles next to search results just the way Google shows image thumbnails in search pages.
To see if your Facebook picture shows up in Yahoo, either search for your own name in quotes and scan through the search page or, a better option, try the following query on Yahoo!
site:facebook.com "Your Name" - check this live example for Michael Parekh.
The thumbnail images are served directly from Facebook servers and not cached by Yahoo! - that’s good thinking because if you update your profile picture on Facebook, it will immediately show up in Yahoo! search pages.

I think it’s a hack on privacy but some people will sure find it the way to glory. Well this can help to search for real people images on web. May be your neighbour?
Yahoo recently updated there semantic web standards for their search. Yahoo now display LinkedIn profile with semantic content, so that even it will show the relationships in the LinkedIn.
