Hate to point it out, but it's a trace. Open that in one tab, then open the one below in another. Make sure they're the same size, then click between them.
I tried opening both images in separate tabs and clicking between the tabs (that's the closest I could get to what you said), and it didn't do anything.
Edit: Oh I see, you mean the artist just traced it. Still, too good not to post. Plus, it's like those templates you see up on deviantart. You take an outline, add a bit, and give it colors of your choice to make it how you want it.
