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.
