The hint about the redirect is missing (" (Redirected from ...)"), the real content of the page is seen on https://en.wikipedia.org/wiki/File:Australian_Christian_College_-_Singleton_Crest.png?redirect=no

I would not expect anything with the file management here, possible duplicate of T16117

I suppose the problem is that https://commons.wikimedia.org/wiki/File:Australian_Christian_College_-_Singleton_Crest.png?redirect=no also exists and overrides the local page on Wikipedia.

There is a way to exploit this, it's rather convoluted though so it's unlikely to happen.

1. Someone uploads File:Burt_Self-portrait.png to enwiki (locally) and adds it to the article for Bert.
2. Realizes the error in the filename and moves the file to File:Burt Self-portrait3.png but doesn't update the filename in the article.
3. Realizes they didn't fix the spelling error at all but just added a "3" to the end, so move File:Burt_Self-portrait3.png to File:Bert Self-portrait.png, again without updating the filename in the article. So in the article it still says "File:Burt_Self-portrait.png". (admittedly at this point the image in the article will break)
4. Vandal who is blocked on enwiki for good reason creates a redirect on Commons from c:File:Burt Self-portrait.png to c:File:Emoji u1f4a9.svg!
5. Self-portrait on the article for Bert is replaced by poop emoji and File:Burt_Self-portrait.png shows the poop emoji as well. File:Burt_Self-portrait3.png is not affected.
