[Fri Sep 03 17:42:45 2004] [error] [client 128.40.78.67] malformed header
from script. Bad header=\x89PNG: mapserv.exe, referer: http://fuji-
bgh.geol.ucl.ac.uk/maps/demos/drought/demo_init.html

Now the Itasca demo works fine - so I'm pretty sure that the installation
is ok.  The problem comes when I try to look at my own shape file.  I'd be
very grateful if someone could tell me what I'm getting wrong. I am new to
Mapserver - so apologies if I'm doing some really silly.

Cheers, Ben
