Yeah, that looks good, but it would be nice if it had a way to specify different resolution copies of the same image for the future when we have varying screen sizes and varying ppi.

Good proposal though, and hope that this takes off.

You know, there used to be a 'lowsrc' attribute for the image tag. (A lower resolution image, which would be downloaded and displayed before the download of the 'src'-image file.)

It apparently is ignored by most browsers now and no longer allowed in HTML5.

Could do it like HTML5 video, and use the figure tag.

    <figure>
        <img src=blah.png dpi=72/>
        <img src=blah_hq.jpg dpi=300/>
        <caption>The fabled Blah stalks it's prey.</caption>

    </figure>

And then your browser could choose the DPI most like your screen.

Personally, I'm skeptical.

I got a bad feeling about this img tag - what if everyone just uses it to post pictures of cats and people making duck faces?! the internet might be flooded with useless content!

It's being worked on:

You missed the flippant humour in the parent.

Why does that is proposal have informal slangy cruft like "poly fill" and exclamation points? That is improper for a stabdard.

Can't you just scale down to half-size an interlaced gif/jpeg and have the browser intelligently decide to stop downloading once it is at sufficient quality?

"Good proposal though, and hope that this takes off." it was a proposal made 19 years back?

woosh

I can feel the breeze of it going over your head from my desk.

does not compute
