     I have been out of school for a long time but all schools used to
have, and I assume still do, an overhead projector.  If you can get
still photographs you can make either slides, with almost any camera, or
transparencies on a copier.  You just use transparencies plastic sheets
instead of paper in many photocopiers.  Many copiers, Mita even has a
special button, have settings especially for photos.
     You can also get a copy of photographer's market from most
bookstores and many libraries and contact the stock photo companies.
