I really haven't checked into what Renderosity allows as far as bandwidth theft is concerned. All I know is that I've visited many sites where the people gave a link to their Renderosity gallery and AFAIK that's acceptable. But just to set the record straight, I decided to do a search for my gallery and at the bottom I found this: "We are proud to host of the works of Kalypso here at Renderosity.com. If you would like to make a direct link from your own website to this artist's gallery, please feel free to do so! Here is the recommended URL, just copy and paste!" There's your mystery all solved I should say :)
