[mapserver-users] ms4w mapserver 5.0 can't display raster image.

Sun Apr 13 20:40:35 PDT 2008

I used Mapserver + Openlayers + Postgis. I can load shp data to postgis and display it without any problem. However, somehow I am not able to display any raster map even without using postgis. I only see a blank rectangular on my web browzer. I wonder whether there is a bug or something I did wrong. Thanks in advance..

I have downloaded ms4w Mapserver and has the following config.
# Apache 2.2.8
# PHP 5.2.5
# mapserv 5.0.2 at /cgi-bin/mapserv.exe
