[Chameleon] RE: Chameleon Digest, Vol 13, Issue 20

Lots of ways to do this and it really depends on your situation. You 
could simply create multiple map files and have the *.phtml file use a 
specific map file as determined by a URL parameter, so 
'http://localhost:8080/john/johntest.phtml?mapfile=testmap.map' would 
result in $szMapFile = "../map/testmap.map"; in your *.phtml file. If 
you have a lot of different options this may not be appealing, then you 
could go with something where you either added a new layer to the 
chameleon application based on the URL parameter or edit an existing 
layer's data property in chameleon to point to a specific image based on 
the URL using php/mapscript in both cases.

Rather depends on what you are doing, number of image options, etc.
