Hi Butch; I think your best bet is just contact the artist of what you wish to use. That way you will know for certain, and from most I have met here they are pretty easy going about using their free stuff. The rare ones that are not, well just find another who is :) By the way it's always a nice gesture to mention the artist in your final product. It's just the right thing to do for their generosity :) Also if you like a million dollars, it won't kill you to give them a little bit of the gross..lol
