There's a little perl script that runs in cgi-bin, and which you could
install in the class cgi-bin directory; you'll find it at:
http://worldwidemart.com/scripts/rand_link.shtml
and I've dropped into /home/ensp482/cgi-bin/aaw5a an example of a different
script that plucks random images from a list; I used this one on the page
http://jefferson.village.virginia.edu/courses/ensp982/projects.html, and
if you reveal code for that page, you'll see how the script is being
called.
