Here's how I think it works, assuming you are a MediaWiki developer
who's written, e.g., a page that includes a thumbnail of an image:
My understanding is that the image scaling/storage infrastructure is
basically only used for user images (upload.wikimedia.org). Code images
generally go on http://bits.wikimedia.org/ and don't use Swift (though
sometimes code may refer to a user image).
