This is a cool feature. It seems you can now make Google Images search for pictures of just faces. There isn’t a command available yet in the user interface but if you append &imgtype=face to the end of your search result url, it will filter the images and just display the ones that are of faces.
For example try these two links:
A search for images of Kuwait
https://images.google.com/images?q=kuwait
Same search for images of Kuwait but with the faces filter
https://images.google.com/images?q=kuwait&imgtype=face
Its slightly geeky but still cool. Check out this site for more details. [Link]
