Fair use for Lake Peigneur
The image linked here is claimed to be used under fair use as:
 * 1) it depicts a non-reproducible historic event (the Lake Peigneur disaster),
 * 2) it is of lower resolution than the original (copies made from it will be of very inferior quality),
 * 3) there is no alternative, public domain or free-copyrighted replacement available.
