Google Imagelabeler is a 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.

Once you login, you’ll be presented a small picture, which will be simultaneously viewed by another participant. You need to give some labels to the picture, just like your partner.If the labels match in 90 seconds, you get a score of 100. Otherwise, another picture will be presented.

So what’s up with this “game”? It’s way of collecting and using people to improve search results, every image in Google’s repository will now be tagged by people like you and me. So next time you search for an image using a keyword, you’ll get a better result. Using people – Web 2.0
