Predictably, this directory contains images of cities other than the City of Chicago. As with the rest of the site, everything here was taken by me, and I'm not equipped to host pictures made by other people, but I can direct you to resources if you have such pictures. In the first case, there is Urban Photo, run by an urbanist in Montréal who often hosts photologs created by other people. Also see Cyburbia, which is an online community for Urban Planners that hosts a public gallery of urban images.
