[mapserver-users] problems with raster, ecw and gdal support

[Pushkar Pradhan]

I think this is happening because when you try to load a jpeg img. the
inbuilt jpeg libs. try to draw the img. before gdal and since they can't
handle color jpegs it fails.
Try compiling mapserver --without-jpeg and --with-gdal support.
