You're linking your dropbox files incorrectly. Just go to your public folder in Windows Explorer, rightclick the image you want, Dropbox -> Copy public link.
hey alpha, the way I link em is to drag em into my dropbox folder, right click and hit view in dropbox website, then click the image in dropbox, and once that comes up hit the thing in the bottom right for "View original" and copy the url from that. just hitting that stupid share thing doesn't work.
That'd be awesome (and a lot of work) if Polycount had a dropbox account that someone added all the art to. Dropbox or something of the same equivalence. But like I said, that's a lot of work for someone.
Yep a 1TB dropbox is soooo worth having. Carbonite is also good for online back up, its not as instant as dropbox but it does all the files on your internal hard drives.
