Map Editor to graphics HELP

Hey Guys

Ok I really about to pull my hair out here been stuck on this problem for 3 days, been using a game map editor to make a hugely and very detailed world map for my Rp forum. But I cant convert into a picture file like gimp or jpeg, and please don’t say just take a screen shot, map to big would take about 60 plus to make complete map, and believe me I already tried this idea using paint to jigsaw the pieces together, the grid alignment is out of whack and this just wont work.

The game is Civ 4 (or civilization 4 beyond the sword) and the map file type is a <Worldbuilder Save>, so if you can turn the file type into a picture type like jpeg or gimp, you will officially be my hero. And your wish will be my command, as long as I can do it will pay you back.

Cheers Loopy
