I don't directly have a photo for this, and it is a break in pace for me. Anyway, there are these things called Schmaps. They are interactive maps of major cities. Well, they just released the New York City one, and I got photos of both Coney Island and the Subway system. Coney Island, South Ferry Station.
I am also up for one for Washington, D.C. and that one should be out next month.
As for how it worked, the process was simple. I just had my photos of the cities uploaded to flickr, and the editor of the site found me. She asked for permission to use them in the short list, and I made it in the end.
