Why not a script? (Score 2)

Well, if the maps are copyright material of the subway, couldn't a script be made, using imagemagick, that could "automatically" crop the image in the requires areas? Granted I never made such a script, but it could even go so far to automatically download the image from the official web site, modify it as needed, and put it into a certain directory. I don't see why this wouldn't be possible, but this sure would stop the problems with copyright stuff if this works.
