File talk:Horse back archery AD 4C.jpg

This obviously isn't the "own work" of the uploader. Presumably what was meant was "own photo of an ancient painting". I don't think copyright applies to photographs of public domain 2-D images either way, so that's not a problem whether or not it is their own work.

But if the photo was taken by User:APoincot could this user please upload a version that doesn't have a "chosun.com" watermark?
