"The" Jason Birch of GIS Blog fame!?! 

Thanks so much for replying.  I am new to Mapguide and am working with MG Enterprise 2009.  I understand that FWTools is an opensource stack of GIS tools and that GDALinfo is a tool specific to reading/writing spatial data, but I don't know if I have access to that through MGE.  I am working with a 64-bit Vista OS, and don't believe I can download and run FWTools. 

Is there another way I could hunt down the info you seek?

Can you run gdalinfo from the FWTools utility package on that image and report back what it says?

I have an 8-bit tiff that is recognized as a bitonal image in Mapguide.  It displays correctly in ArcMap as a raster with 10 values, but in MG it's only black or white.  Any ideas as to what the issue is?
