[Mapserver-users] CGI can't read WMS using image/png files

[Tyler Mitchell]

I'm stumped using v4.2b3.  My WMS client connections work great, unless I 
request a image/png format.  My MapServer creates png images but can't 
seem to read them, which is doubly confusing.   Even stranger is that 
shp2img works great, but not through the CGI.  (Hmm, perhaps I only tried 
it with that single layer using shp2img but not with CGI and that is the 
problem?)

I had read something similar which pointed to gdal - libpng - mapserv and 
which png libs were compiled into either.  AFAIK I've successfully built 
them against the same libs.

Any ideas?  I can give more detail (I admit that it's lacking) but 
wondered on the surface if anyone is hitting this?
