You can, however, legally download the texture map for free, then paint one of your own. The color scheme doesn't look too complicated, I'm sure that it wouldn't take too long to paint something pretty good. If you're not up to the task yourself, I wouldn't be a bit surprised if there isn't someone around here who would be delighted to take up the challenge as a favor, one artist to another. Be sure to scale the map up in size, before painting, to get the detail right, then scale it back down to a reasonable size before saving, based on how detailed an image you want to create with it.
