Yes, the original contributor's image was very very... "no comment".
Thanks for the compliment on this image. I want to do much better, though-- the sky looks too photoshopped, the leaf looks too stylized, the entire image's colors look to simplified, the surface of the water looks too abrupt, yadayadayada.
It was pretty easy contributing this image to Wikipedia and Wiki Commons. The registering of my user-name took a few seconds, and this image appeared almost immediately: [link]
That's both gratifying, and a little alarming. I mean, what if I'd uploaded a JPEG with an ad banner in it, and just PRETENDED it was an image of a prehistoric amphibian?
