Details

Not sure this is valid or if we already do that, but AFAIK we block rendering or have to re-render when an <img> tag's dimensions are not known until we have the image file header. Loading such images sooner may shorten the perceived load time of the page and save some reflows. Or am I completely out?
One of the CCd people will know.

This sounds reasonable to me.
