The image was credited to another website, but the page on that second site did not exist, so it was unclear if they actually got it from wikipedia. The uploader has created other images for WP, and there is no reason to disbelieve the claim that the image is his. J JMesserly (talk) 06:09, 30 May 2012 (UTC)
