Hello Chapeaumeulon, your uploads are incorrect. There are many paintings by Lucas Cranach the same title or title variations or with several titles. This painting (File:The Fall of Man by Lukas Cranach.jpg) is this. The missing any references is bad. This may be a temporary problem. Perhaps the painting not by Lucas Cranach the Elder, but by his son, from his workshop or by one of his students. We do not know. Nevertheless, it can not simply be swapped with another image. The other pictures are already on Commons Wikimedia. Look into the category Paintings of Adam and Eve by Lucas Cranach the Elder.
Your uploads were unfortunately also not referenced. „Wikipainting“ is very inappropriate, because they have the image from Commons Wikimedia. A better reference, the museum web-site would have been: bilddatenbank.khm.at. --Botaurus (talk) 20:05, 25 August 2013 (UTC)
