The Live Search team blogged about a few updates that they recently added to their image search page

You can now filter image searches to help you find images with faces, portraits, or black+white images. When you search for people, you also get a list of related people on the right side of the screen.

A few examples: 
  1. without the new features – jimi hendrix
  2. with new face filtering on – jimi hendrix filter:face
  3. with new portrait filtering on – jimi hendrix filter:portrait
  4. with new black and white filtering on – jimi hendrix filter:bw

Congrats to the Live Search team!
