This site has been collecting school photos for people who've lost their own and would like some way to recover a print. You have to have been in school no earlier than 1950 (so sorry to all the old people). While I wasn't able to find mine I did find pictures of some of my friends which is pretty cool. So, if you or someone you know has lost a school photograph you may check this site out.
Note: Schools voluntarily give photos to this site and have the right to refuse participation with this site.
