Quiz #23: Twenty for Ten

Below are twenty well-known photographs by twenty different street photographers, each cropped down to a square 100 pixels per side. How many can you recognize?

Answers score one point for each correct identification. I will add another round of clues Friday, after which correct answers score 1/2 point. The person who first emails me the highest point response before Sunday, 10/10/10, at 10:10 am PDT wins 10 by In-Public. Good luck!
