I just took a quick look at the terms for uploading images here and it seems as if Renderosity is not assuming any rights to use any images uploaded to their gallery, even for self-promotion. I'm a little surprised, but it's very refreshing, especially after abandoning entering the 12 Months of 3D contest sponsored by DAZ & Deviant Art and the nasty agreement involved in that. I've seen some galleries that allow the host to use the images for marketing purposes, but don't find anything offensive in that. It's interesting that the Renderosity gallery doesn't even ask for that right. About the only agreement is that the artist retains the copyright.
