By official, I mean 'from an official source', not 'used in an official capacity'. But, yes, perhaps professional would be a better word. The 'photo attribution' tag does not look professional.

(As a side matter, I don't understand why 'photo' now seems to be replacing 'file' and 'image' when very few images I've seen on wikis have been photos. It just seems designed to appeal to the social networking crowd.)
