That is maybe a slight misunderstanding. In the case we are talking
about the layout will be known to the browser since we have told the
height and width of the images. So scrolling is not affected. If the
image is not loaded there will be a gray rectangle there instead.

Of course loading the image may require some CPU cycles. I am not sure
(without testing), but in most cases I think you will not notice that
very much.
