a new feature of Google Image Search that allows you to label
random images to help improve the quality of Google's image search
results.
How does it
work?
You'll be randomly paired with a partner who's online and using the
feature. Over a 90-second period, you and your partner will be
shown the same set of images and asked to provide as many labels as
possible to describe each image you see. When your label matches
your partner's label, you'll earn some points and move on to the
next image until time runs out. After time expires, you can explore
the images you've seen and the websites where those images were
found. And we'll show you the points you've earned throughout the
session.
