This question concerns how your server handles server-side
imagemap processing. Recent servers provide built in support for
imagemaps. These include recent versions of NCSA, Apache, phttpd,
and others. Older servers may require an external CGI program to
handle imagemaps. CERN servers often name this program "htimage".
NCSA names this program "imagemap". WebMagick requires the relative
URL to this program if your server requires it. Typical answers
will be "/cgi-bin/htimage" or "/cgi-bin/imagemap". If your server
does not require an external program, just hit RETURN.
