[Mapserver-users] TIFF-Display

 Is there an image conversion
> tool to produce TIFFs that mapserver can show?

I use Imagemagick's tools quite regular; never encountered problems using 
these images with mapserver. Usually, I convert images with it to 8 bit, add 
a .tfw file and use gdal_translate to add a coordinate system, if needed. 
Works as a charm.
Btw, you can use gdalinfo (I suppose you have compiled gdal?) to get 
information about your tiff, e.g. if it is really still an 8-bit 256 colors 
image...

Cheers,
Vincent.
