I have a couple darkroom montage and screening projects where i'm in need of stock image related slides and negatives. I can't seem to find any. After searching ages online I know very few that had some but most were travel style photos and/or were individual exceptions.

Does anyone know a place/person that can send you a couple either to borrow or as dupes or even sells royalty-free images on large or small negative or positive transparency? and of course i'm looking for nothing fancy or remotely expensive (more like the stuff on a photo stock $30 cd; isolated subjects-objects-backgrounds-textures etc...
