The original version of this answer had an imgur image embedded in it (original edit). I've just now approved an edit which removed the imgur link because it was broken. I remembered seeing a bunch of meta posts regarding broken imgur links, so I revisited them, however possible alternatives of http://i.imgur.com/JSMG8.png and http://i.stack.imgur.com/JSMG8.png both still produce no result for the ID of that image (the URL http://i.imgur.com/JSMG8.jpg produces an image of a cactus - but I'm sure that's not related to the answer, so it seems that the generated names for the uploaded images are not that unique).
This meta answer from 2 days ago indicates that some work has been done to regenerate some HTML of old questions/answers, so possibly the problem lies with those changes.
Is there a way to determine whether that link was always broken, or whether some recent changes have broken it and it is possible to restore it?
