From CC BY-SA 3.0, section 4 (c): at a minimum such credit will appear, if a credit for all contributing authors of the Adaptation or Collection appears, then as part of these credits and in a manner at least as prominent as the credits for the other contributing authors.

I don't feel that crediting some authors on the articles and others on the file pages is following the spirit of this license.
