    Locking Desktop & Screen Saver Function in Mac Lab?

      I manage a 38 computer Mac lab for our art department and I am having trouble with students changing the desktop image everytime another teacher uses the lab.  You can just wonder the type of images that have become popular&*^&*&%*&^))(*!!!  So every time I enter the lab my students are blasted with the images that have been saved, I am assuming, jsut before shut down so the teacher cannot see the results.  Is there a way to lock that in System Preferences?
