Forum:International covers

I noticed that there are a few images of book covers from different countries in Category:Covers, such as this and this, but most of them are not used on any page in the wiki. Is there any particular reason they're not on the pages for the respective books and/or Cover art? I added the French cover to the gallery on Harry Potter and the Philosopher's Stone, which had all the US and UK covers and the Dutch one.

This page has covers for all 7 books in 6 European languages. Would it be OK if I uploaded those images and added them to the respective book pages, using the same format I did on the Philosopher's Stone page for the French and Dutch ones? Or would it violate the image use policy, since that's not an official source? If that source isn't OK, would it be OK if I found the images on the international publishers' websites? (That would be more difficult, but probably not impossible.) I think a gallery of translation covers would be a good addition to the cover art page, but I don't want to step on anyone's toes or go against a previous decision. —Josiah Rowe 16:08, November 23, 2010 (UTC)
