[mapserver-users] web development project with mapserver- questions

David
Thanks for the response.
 
Divs arent a requirement; I just mentioned them because the example site that I posted was using divs, so I suggested them more as a point of reference. 
 
Id be willing to use whatever works, but Id obviously like to avoid using any hefty solution that could be considered as being 'overkill'. something simple & lightweight is prefered.
 
Im not very experienced with mapserver, but would the use of symbols to add the vector drawings be a feasible solution? can symbols show up on the image map as clickable regions with mouse-over text?
 
i.e., something like:
1) use my backend code (php/perl) to generate the markers & select the appropriate symbol image file & "alt" text
2) pass this info to mapserver prior to drawing the map, & include the symbols into the map image.
3) create the image map with symbols
 
does this method sound reasonable/right?
 
IF so, how would I go about this (creating these custom symbols)?
Is there an existing tutorial that might help me accomplish this?
 
Thanks again,
P.Romero
