Hi, no, the source was the article:
http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0001031
That page states "Copyright: 2007 Adamska et al. This is an open-access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited."
So I uploaded it here. Some automated movement of files (or something along those lines) has led to the image page listing me as the "author", that should really be the "uploader". Evercat (talk) 00:00, 23 July 2015 (UTC)
