i use photoshop cs3 almost exclusively when making maps. I've dabbled with ill a bit, but have much better results from ps.

I do not use ArcGIS or any other mapping programs (besides maps.google) for reference. But is there software, hopefully free, that will allow me to import black and white bump map type terrain that I can incorporate into my maps?

I guess sort of like this from www.xnrproductions.com

i would like realistic terrain as a soft map background texture. Thanks for any advise or links you pros can provide.
