I'd have to definitely take a look at some tutorials for using Photoshop then. My wife uses it to touch up photos and such, but I've never played with it, myself. Looking at his map, I wasn't sure if he used something like that, or another map drawing program, like CC3 or Dundjinni. For now, I think something like those would be along the lines of what I'm looking for, although learning how to use PS or even GIMP wouldn't be too bad.
