As for media files, they may be licensed differently. As I import them in bulk I can’t give a proper attribution and licensing information for each and every file. But for each file you can easily find a corresponding original file on Wikipedia and read licensing information there. To make things easier for you I provide a link to corresponding Wikipedia article on top of each article on this site.
