[mapserver-users] Can't get a raster to display... projection issue?

Hi all, I'm brand new to mapserver.
(The itasca workshop map works)

I can't get a raster to display. I've tried various extents and projections
but suspect these are the cause. The mapfile is as below (IMAGEPATH and
IMAGEURL are changed -- working with itasca) as well as info from gdal.
Your help would be greatly appreciated!

Thanks,
Pete
