Need B&W photos for 35mm short film

The film is a horror story and has a fairly big budget for a short. We've built a set and dressed it, but can't afford to pay for good photos to display on the wall. If you give us permission to use photos in the film, we would make prints of them, hang them around the set, and give you a credit in the film, as well as a copy of the finished film.

We're not looking for any particular subjects, could be anything from nature to portraits, preferably Black & White.

EDIT: Great photos everyone! We found some we liked and rushed to get them printed. Would love to stay and compare them all, but we have a million other things to do.
