I own that game too, yet I don't have the box anymore...for whatever reason.
Do you mean you're not allowed to link the pic? In that case, just get a free pic, like without any logo from websites, and copy it.
It's considered bad etiquette to take a picture that someone else scanned or photographed without asking permission. Some even go so far as to claim copyright ownership to their specific reproduction, but most get mad simply because they put in the time to acquire the original and scan it.
As such, sites such as Wikipedia and the Compendium prefer that images published as a part of the site be created, scanned, or photographed by the contributor himself, since it avoids a lot of possible trouble. Of course, scanning a copyrighted image and slapping it on a site without permission is still technically illegal, but using it as a part of an article -- as opposed to a simple image gallery -- can be argued as fair use.
