Back when I first tried opening the page it 503ed and there was just one page of comments, one of them was this image link. Its purpose was fairly clear, actually. And helpful.
No it's not clear but it was helpful. There is an implication that a simple imgur link could be a mirror of the comic image. But then you would have to know that the content of the article was a comic image.
The original page 503'd for me as well, and I wouldn't have known that the imgur link was a mirror if it wasn't for the replies to it (since I just Cmd+F "mirror" to find this).
