You're welcome.
If I recall correctly, GIMP does have a color range select thingy somewhere in the menus or tools, and I'm 50% sure it has masks... but I'm not sure how easy they are to adjust. You might download a copy of Photoshop CS2 if it's just too much for GIMP to handle.

My apologies. I thought it had been released as freeware.
Ah, no I see... an older post in the software discussions forum had caught the corner of my eye, but the widely spread rumor on the net appears to have been a misinterpretation of phrase.

Well thank you everyone for your help: but I have seen my limits and will have to start from the beginning at http://www.cartographersguild.com/tu...y-mapping.html to get a better education in this subject.
