When trying to find old yearbook pictures, it is usually best to go to the website of whichever school or college you want to see. Alumni associations are useful for keeping in touch with old classmates, and if there is one for the high school that you left then it might have some yearbook photographs on it. It is likely that an alumni association will have some old yearbook copies; if you are a member of the association then this may be helpful. Groups associated with your old high school may be found on Facebook, Twitter, or MySpace, so it is a good idea to check those. There are sites such as classmates.com and reunion.com, which can help you get in touch with ex-classmates, however these do charge you for the privilege. The answer on wiki.answers.com/Q/Where_could_one_find_their_old_yearbook_p this link was particularly helpful in answering the question, which was my main source.
