I am currently looking for 4 types of photo sourced images
Building facades (shop fronts, upper sections, offices etc)
Road and pavement textures
street furniture
and cars,vans etc (shots of the front, side and back)
I already know about CGTextures and the usual rounds (environment-textures.com, mayang.com/textures, imageafter etc)
If someone has a largeish collection of these types of images (not from the websites listed above) I would happily chip them some money (not vast amounts but a little for their work)
If you have abandonned, burned or ravaged images of buildings thats a +
