[mapserver-users] can't display TIFFs

[Dylan Keon]

I can't seem to get TIFFs to display using MapServer...I get either a blank
page or a "server not found" error.  I'm using a modified version of the
Europe PHP example (nothing fancy), and I can display shapfiles just fine,
unless the raster layer is included in the mapfile.  If I comment out that
raster layer, everything displays fine once again.

I've tried three different TIFFs, with no luck.  All TIFFs are in the
correct projection & datum, are 8 bit images, and display fine with the
associated shapefiles in other applications.  The TIFFs were created using
the GRIDIMAGE command in ArcInfo, and I renamed the .tfw extension to .wld
(tried it both ways, actually).  And it's not a permissions problem.  I've
tried both colormap and grayscale images, with no difference.  I followed
the "Raster HOWTO" instructions, and the "Converting ArcINFO Grids to
Mapserver TIFFs" instructions in the Wiki, but neither helped.  Am I missing
a format from GDAL or something? (see below).  I compiled
Mapserver --without-tiff.

Thanks for any help, not sure what to try next.
