I'm both surprised and dumb-fouled that one could upload a HTML link onto Danbooru. Well more dumb-fouled than surprised.

Really annoying. How do you upload a jpeg and get the MIME type wrong? The fault lies with the source in this case. I almost uploaded this same thing again just a minute ago. Thankfully, despite this from iqdb--
Retrieving http://utakata0824.web.fc2.com/img/201006132 (628 KB)... failed
201006132: Not an image or image format not supported (server says it is text/plain).

...I bothered to save and check with a proper MIME. Now, shall we change the source URL?
