Ok so we agree that the article isn't rubbish right?

Now with that's out of the way, a few things I want to outline: 1) The default value of background-attachment is "scroll" (it's never "fixed", in IE or FF or Opera)... that said your initial guesses weren't really correct. 2) background-attachment specifies whether the image is fixed or scroll with regard only to the viewport ( http://www.w3.org/TR/CSS21/visuren.html#viewport ).

So to this question:

The image does display but its position is at the top left corner of the viewport, outside of the #page container. Just resize your browser window of the "version 1" you'll see the AU map image.
