Anselm,

Seen this today, to remind people that it is not just
something up in the air. People need it.

I wonder if it could be handled by CSS in fact.
I guess Anselm, you could ask there.
On the www-style mailing-list, Charles proposed [1]
content: url(img.jpg) replaced;
Oh, that's not my proposal, that syntax was brought up by Tab Atkins.
It's already available. I was looking into how to handle <img [no
source] style="background: url(..)" />
It may work with the following, now, or at some point in the future:
<img style="content: replaced; background-color: ...;" />
I'd proposed visibility: content-hidden; to be used with background and
border.
I'm not sure I fully understand the proposal
but we can imagine something that could fit nicely
with the CSS Generated Content Module Level 3 [2]
<img class="responsive" src="http://example.org/foo"; alt="wiizz"/>
and then the CSS
@media screen and (min-width:550px) and (max-width:960px) {
img.responsive {
url(http://example.org/foobis) replaced;}
}
@media screen and (min-width:240px) and (max-width:549px) {
img.responsive {
url(http://example.org/footer) replaced;}
}

Keep in mind that min-device-pixel-ratio is also useful to monitor.
Set image dimensions in the css style to prevent reflowing.
