If you use an image with a recognizable person who doesn't want it published in a commercial way - and fodder for a site with advertising is absolutely commercial use - it's legally actionable. People don't have the same legal right to privacy on the sidewalk that they enjoy in their homes. You can take a person's picture in public, this is completely legal. But whether or not you can use it, and how, is a much more complicated issue.
