I can get around the problem simply by posting the map exclusively on the WotC site - their own rules facilitate this (ANYTHING posted on their site becomes their property - there was a bit of an uproar over that some time ago). If I post THEIR property on THEIR site, their property (and anything I have added to it) then becomes theirs (again). That will probably work in regards to keeping them happy, and I can post links here and at Candlekeep to the relevant thread over at WotC.
I 'think' that will work....
However, that might just upset Mr.Shley all the more, which is something I DON'T want to do. I will have gone completely around him to the people who have bought his art from him, which he may construe as 'stepping on his toes', and like I said, I RESPECT and ADMIRE him. I specifically take-on obscure projects knowing full-well that they (WotC) will never actually pay anyone to produce what I do (mostly conversions), so as not to take work from real artists.
And like I said, its a little more then textures - I've created patterns with his terrain, and although I have tweaked the heck out of them, they are still easily identifiable as his work (which was really the whole point).
