Hello, thanks for responding so quickly. Could you please forward his mail to "permissions-en (at) wikimedia.org", so the license can be properly confirmed. I hope his wording was explicit in such a way that everybody will be allowed to use it, not just we here on Wikipedia, because otherwise we'd unfortunately be forced to decline (see WP:NFC for reasons). If you managed to get a real free license for this image, good job! It's a beautiful picture.

 BTW, below is our standard "welcome" blurb, just in case:
