Thanks for the example and explanation, but I see "Regular | Pajamas Uniform  Slayer  Prom" all as working links, and clicking them switches the image correctly.

This page also displays both "new" and "old", and the links work.

Edit: But, after refreshing the article, it doesn't work: sometimes it works, and sometimes it doesn't, so I suspect a race condition, and I don't think it would have to do with a Wikia update, but also I don't know why this only just started occurring.

The javascript console says "Uncaught TypeError: undefined is not a function" in relation to "elem.className.split"
