It's upto moderator's of the site to make the call but as a member of Renderosity I'm highly against this "feature". It just make the regular visitor's life more difficult and it surely not protect images from thefts. If the moderators want less people to hang at their server this is the way to do it. Somebody above also mentioned that people should ask from the artist if one wants to download the picture. That's true but how would you like it if one day you check your mailbox and see couple of thousands messages titled "mee want tiz too" ... ? Those lamers who are stealing the pictures for their own financial use can't be stopped until the picture does not exist in the internet - and we all know this: "once x is shared for the net it forever remains in bitheaven". Artist are those who make decision about their work. If you make a piece then you don't have to share it! But what is an artist without an audience? And you can always add your "signature" to the picture as large as you like so no one can missuse the piece or shrunk resolution to 400 pixels and something .. (wallpaper freaks probably slate these few last ideas;)
