Wait a minute... you don't mean HeroImage by any chance? I notice that the wiki has this Special:WikiFeatures Labs feature enabled, but there's no image. It's not a template, so it's no wonder we're confused.

EDIT: Yeah, it is. I see that the code says

and that it was manually added (I know because the image isn't supposed to have a file extension). Delete it, and add the image properly using the Add Cover Image button at the top right of the front page.
