Indeed, it's called Special:Miniupload. There doesn't seem to be any information
on how to obtain it. Perhaps it's a wikia-only extension.
Thanks for the pointer!

I think that Wikia has something what you are looking for. You can see
example here
http://www.wikia.com/index.php?title=Wikia:Sandbox&action=editedit, it's
the
last icon/link (green arrow) in edit toolbar menu, but you need to be
logged in.
