Perhaps it's unfair to mark down a program that does exactly what it says if you read the description carefully, however, it doesn't do what I thought it did. Judging from the other reviews here, I'm not alone in being confused. I wanted something like in Google's Chrome where you can right-click to get a menu and then choose "Search image" to search for images similar to the one clicked on. However, this extension doesn't do that (yet). I hope the author will eventually add in that functionality. In the meantime, I've switch to TinEye reverse image search.
