Your recent uploads (example) list "own work" as the source and you as the author. The author is for the name of the person who created the works (the original artist/publisher). Source would be where you got them from... such as the URL of a web site, the name of a book, etc. – JBarta (talk) 22:50, 13 April 2012 (UTC)
