It should be easy enough to write a quick find/perl hack that can print
out a list of all the files actually being called via <img>. If you're
using Javascript to do rollovers, or to manage images at all, it gets a
little hairier to detect.

cd $web_doc_root
find . -name '*.html' -exec perl -ne \
'if(/<img.*src="?([^"\s]+)["\s]/i) {
   print "found one: $1\n";
}' {} \;

something like that, anyway. You might want to store what you find in
an associative array instead and just print the list at the end. You can
then resolve any relative linking issues (e.g. "../../images/") and go
through and do a find on image files, compare to see if they're in the
list, and voila. Shouldn't take long.
