Showing multiple layers using one checkbox

[Bradley Mclain]

Thanks I created a static image showing the layers I want, only problem is 
that once the mapserver invokes the map, the image fails to load because it 
has the mapserver-cgi directory infront of the image path, how do I avoid 
this?

Image Declaration:
<td>
<p>Legend:<br>
<img src="legend.gif" width="159" height="77" border="0">
</td>

Broken Path:
http://192.168.1.130/cgi-bin/legend.gif

Also on the same note as this currently my map does not show up on first 
load you must click on it to get it load. It would be much better to have 
the map load on page load. I will include the html file as well.
