The worst part about server side image maps is that it completely breaks archiving. So many times I've tracked down an old website address on archive.org's Wayback Machine, only to find that the homepage is one big server side image map. Without the original server, there's no way to discover the destination URLs for the rest of the site. It's a complete dead end.
for a list of every archived page from the site. It won't include pages archive.org doesn't have, but without the original server, there's no way to get those anyway.
