You're right. I was thinking that the values (Nh Nw Nx) described the *image* but in fact they describe (in the case of Nh and Nw) the viewport and (in the case of Nx) the pixel density of the screen/device.

I suspect I won't be the only one to make that mistake.

I can see now how it does handle the art-direction case as well. I think it's a shame that it's a different syntax to media queries but on the plus side, if it maps directly to imgset in CSS, that's good.
