That may seem like an odd request but its something that is an interesting exercise, if a bit revealing as well! Did you know what photos of you are up on the web and did you know how they got there? Did a friend upload a shot with you in it, was it a Christmas party photograph? Once its on the web it is tough to get it removed. Even this article from Google themselves is not very helpful HERE
What you can do is make sure that all the photos you upload of yourself are the best they can be or at least showing a side of you that you don’t mind the world seeing.
