Have your ever noticed Google Image Labeling, its like a game that you can play with somebody that you don’t know. Ok I will tell you how does this work. Just go to Google Image search and search for something. At the bottom of the search result page, you will see something like this

Just click on the Google Image Labeler link.

How does this work?

You’ll be randomly paired with a partner who’s online and using the feature. Over a two-minute period, you and your partner will:

• View the same set of images.
• Provide as many labels as possible to describe each image you see.
• Receive points when your label matches your partner’s label. The number of points will depend on how specific your label is.
• See more images 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.

You not get paid any cash, its just helping Google to label the images and give a better search result
