I believe the guy who painted that image was commisioned to do it for the Horus Heresy artbooks, which are published by the black library, but I could be wrong.
This could explain your problem.. The image, I believe, is not owned by GW at all. It's printed in an artbook, and there'd be no point selling an artbook if all the images were available in decent format over the internet, would it.
