Script Summary: Adds a checkbox to enable "Face-Only" searches in Google Images.
Hunh. As it turns out, it doesn't work on the result page, only on the main images.google.com page. The more you know. If someone wants to take a look at why the checkbox is ignored on the results page, let me know what you find out. I'll update the script and credit you.
Honestly, I'll probably never use this, so I'm not going to spend a lot of time on it.
