[mapserver-users] .map

John,

If the most you can view at any one time is one gif, then keep it 
VERY simple. Have the user select it based on any area, product
 type and date and dynamically define the file for the layer which 
will show that image. I think you can doe that without any mapscript, 
just using the CGI parameters.
