Ok, I don't know why this is such a difficult idea for people to grasp, but let me try again:
Yes, leeching is bad, but posting the image on another server wouldn't be any better. In this case, the author's message states it's copyrighted. You can't post copyrighted material anywhere without the author's consent.
Secondly, it's against Head-fi's term's of use, see the author could find this pic, and complain very loudly to Jude.
But even if it weren't copyrighted, it's still very bad form to post it for download without the author's consent. On reputable customization sites like wincustomize for instance, if you don't have a text file with the author's permission in it, you'll get the banhammer so fast it'll make your head spin.
See, someone actually made that picture you're using, and to find it for download on sites without your consent is just plain rude in some cases, and a copyright violation in others. It's known as "ripping."
