These coordinates are already sent to your server application when
clicking on the map: IMG in image coordinates (more specific IMG.X and
IMG.Y), see http://mapserver.gis.umn.edu/doc/cgi-reference.html and 
the Itasca Demo http://mapserver.gis.umn.edu/dist/itasca3.5.tar.gz
for more.

However, the QUERY functionality should provide what you need out of the
box. Again see the Itasca Demo and play around with the TEMPLATES.

regards,

        Frank
