It wouldn't take up so very much space if Renderosity hosted the thumbnails. Much less space than is taken up in Renderosity by all the art galleries and all the pictures sent in with messages. That would leave onlly the downloads to be hosted out. In old times clicking such a download ink-in-from-the-side on many free webspace providers got the provider's advertisement page, which included a clickable leading to the download; that can be done with a zipfile for download but not with an embedded .JPG or .GIF graphic. Perhaps if Renderosity hosted the thumbnails, free webspace providers might become more willing again to let people link in from outside.
