The best were started by Despair, Inc. I'm uploading theirs with :-( in the title. They have recently started a feature where you can upload your own picture, naturally so they can ding you for more of your hard earned money while you are unemployed. Hahaha.

There are BUNCHES of what we want in Google images now. Remember, we don't seem to be able to upload .png images, just .jpg and .gif
