Update: Got messaged, the original photographer/owner of the image used for "Stripey Sepia" replied to a message sent in November, and says that permission for said image was never given and his request for removal was ignored.
This goes against what Nova claimed in a comment thread below (That they were okay with it, and didn't ignore him):
And said the same on DA: http://imageshack.us/photo/my-images/6/stripeysepiabynovawuff1d.png/
