IMO Koops our illustrations are free of those copyright photos or renderings laws, because we are not using them. We are just basing in a public information, while they are spread officially in public to be known and we make our own illustrations based in our talent to understand the message only.. So we are not using and reproducing such renderings or photos. We base in a well know spread info to make ours and of course, they will be never equal exactly traced off on them. It is why that is not allowed here. Otherwise the talent can not be copyrighted in transmitting the same appearance in other material. Just photos that are diagramed pixel by pixel or diagrams taken out from those photos or part of them, that are not allowed. It is much more worse the photos and renderings just cut from the owners and copied & pasted in Emporis for example.
But I think the best who can tell us about is Mike K.
Is your Equinox the same like that?
