Fireworks has a tool called pattern. I was wondering what is the legality of selling that patttern (Either being used as part or most of an image)? Do you have to purchase the pattern form Adobe first? If you modify it enough can it be claimed as your own? If so how much different does it need to look?
As long as it's part of an image you created in FW, there's no problem. You may not sell copies of the pattern itself, however.
