Tim explains why that neat trick of making a really big JPEG with quality set to 0% is no longer necessary, and how the savings you make in bandwidth with that technique are nullified by the expense of the memory footprint needed.

Jason revisits responsive images. On the whole, things are looking good when it comes to browser support, but he points out that
scrset’s precursor in CSS—
image-set seems to have dropped off the radar of most browser makers, which is a real shame.

The transcript of a great talk by Wilto, focusing on responsive images, inlining critical CSS, and webfont loading.
When we present users with a slow website, a loading spinner, laggy webfonts—or tell them outright that they‘re not using a website the right way—we’re breaking the fourth wall. We’ve gone so far as to invent an arbitary line between “webapp” and “website” so we could justify these decisions to ourselves: “well, but, this is a web app. It… it has… JSON. The people that can’t use the thing I built? They don’t get a say.”

Following on from that post of Jason’s I linked to, Chris also emphasises that, for most use cases, you probably only need to use srcset (and maybe sizes), but not the picture element with explicit sources.
It’s really, really great that people are writing about this, because it can be quite a confusing topic to wrap your head around at first.

Jason points out that the picture element might not be needed for most responsive image use cases; the srcset and sizes attributes will probably be enough—that’s what I’m doing for the photos on my site.

Surfin’ Safari - Blog Archive » Improved support for high-resolution displays with the srcset image attribute
WebKit nightlies now have support for
srcset. I’m pleased to see that it’s currently constrained to just handling the case of high-density displays; it doesn’t duplicate the media query functionality of
I’ve always maintained that the best solution to responsive images will be some combination of
picture: they each have their strengths and weaknesses. The “art direction” use case is better handled by
picture, but the “retina” use case is better handled by

Wilto does an excellent job of summarising the current state of responsive images, highlighting Florian Rivoal’s compromise proposal that combines the best of the picture element with the best of srcset.
