Re: Informing the browser of the expected size of the image

Simon, I'm not sure I follow.. I think what you're describing is orthogonal
to what Kornel and I are saying.

With HTTP/2 the server can send the first KB (or whatever amount) of the
image to allow the browser to decode the image header and get the geometry
of the image much earlier.. which minimizes reflows during initial page
load (which is awesome).
