[respimg] a perfect responsive solution should not tamper the HTML syntax with too much repeating information

I have worked with optimizing my CMS and websites/campaigns since 1997, and
for the past 11 years in my own company.

My solution to responsive images is to the the SERVER do the tricks.

Not the browser. All we need on the server is some more information from
the client on "who you are" in terms of the resolution.

So perhaps the screenresolution should be part of a HTTP GET request?
instead of the first page has to use javascript to pull these data and then
store them in a cookie the server can look at. Because the problem is the
very first hit on the website, as you dont have any cookies telling
anything regarding the resolution or layout of the client.

My proposal would be that we keep the very nice and clean structure of a
simple <img src="fooimage.jpg" alt="" title="" />

then is completely up to the server to handle this correctly based on the
forwarded resolution sent to it by the client-browser. If nothing is sent,
use defaults.

.... What about resizing then? well, yes, since the image needs to be
supplied in different sizes, that ought to be cutout on the server before
we release the page anyways. Ofcause this could be automated if you have a
good crop/scale mechanism in your CMS (as in the one I am building :-) )

But the idea of melting a lot of extra "in-line CSS" kinda mess in a single
img tag is horrifying to me.

A HTML document shouldnt contain size/dimensions. It should contain
CONTEXT. The details about colors, size, dimensions is for CSS and other
similar schemes.

Lets keep things seperated so they can be optimized on their own.

I know a lot of people would love to code everything by hand and therefore
doesnt see the problem with the extended src attributes. but look at the
amount of extra bytes in every page you are going to make responsive. Will
this stop at 3-5 sizes? nooo suddently Apple or Google release some new
device and then we all have to fix every single image on every single
webpage because its stored directly in the HTML and not a part of server
image handling system.

Come on, we are in late 2013... we can do better than cluttering up the
HTML with inline-CSS.
