[mapserver-users] Question on linking external info

[lists]

Hi

I recently started looking into MapServer, and have MapServer 3.6/PostGIS 
running. Very nice !

I was looking at the Recreation Compass at 
http://www.dnr.state.mn.us/maps/compass.html and was wondering how they 
implemented the external info when clicking on certain features in the 
map. 

For example, on clicking one of the pink "Scientific & Natural Areas" I 
get a new browser window with Information/photos etc about "Lost River Peatland 
SNA" ... generally speaking, what is needed to achieve this ?

Any help would be much appreciated

Regards and Thanks
