[Mapserver-users] RE: querymap with WMS GetFeatureInfo

[Kralidis,Tom [Burlington]]

Hi,

I think I may have figured it out.  Putting this in my footer.html for
the query template of the layer (with querymap defined in the .map file,
of course):

<img
src="/cgi-bin/mapserv/envirodat?mode=querymap&img.x=[img.x]&img.y=[img.y
]&imgext=[imgext]">

..works as expected.

..Tom
