I noticed that some people add credits of photos inside the articles,
saying that CC-BY requires attribution.
Shouldn't photo credits be allowed *only* in the image description page?
I don't see why images would have a special status when compared to text
contributions, the credits for which are found also a click away, in the
edit history.
AFAIK, there's no policy disallowing photo credits, but there should
be one clear policy to discourage that -- it would also be a place
to point people when asking about that. :-)
(I'm not referring to photos by famous photographers who have their
own articles, but to photos uploaded by users or found on Flickr)
