Hi Paul,
aside of all the technical reasons that have been given, the most relevant
reason you should not use MQ for responsive images is the one Tady Walsh
pointed out: accessibility.
*Images are not style*, *but content*, so they have to be accessible
without CSS or JS and they need an *alt* attribute to be fully accessible
and an HTML tag to be semantic. And by accessible I mean not only for
disable people, but for Search Engines too. Do you think Google is going to
index your design images, not even knowing what is in it?

Also they start loading before the CSS images do, as a couple of mates said
before, and they are part of the structure and the content, both at a time.
There are to kinds of images, the one used for styling that should be
loaded by CSS, as you said, and a content image, that illustrates the text
and/or in some cases represents 80% of the whole content. *How can we
pretend to control by CSS a CMS content? Thousands of images...* is not an

Me my self as a layout designer and UX, I'm not very happy with the actual
solution, but I agree it must be a DOM based solution, not a CSS MQ.

People here have been working a long time to get with this solution, *we
should try to read and understand why is it like this, how it works and
what does it pretends*. Then, maybe, we can bring a new solution if we are
capable too, but what we can't do is to ask to those who have been
selflessly working hard to develop and test a solution, to work for free
just to demonstrate us, that their solution is not wrong, just because we
don't have the knowledge to understand it by ourselves!!

Hope you get the point.

best regards,
