The picture spec has landed in both the WHATWG and W3C specs.
Simon Pieters, hero, took on responsibility for all of the image-related bits of the WHATWG spec in order to make this happen. Simon included a nice, “non-normative” (aka “informal” also known as “readable”) introduction to the new markup along with all of the technical bits.
And, hey! Look who popped into the W3C HTML spec’s list of editors!
Not bad for a Community Group.
Mike Smith, who maintains the W3C HTML Validator, is adding picture spec support; it should land within a fortnight. The under-development picture branch is up and running here, armed with boatloatds of useful error messages – go test your code!
Can I Use has begun tracking picture support.
And Google’s new and wonderful Web Fundamentals guide now features the new markup in its section on content images.
Firefox Nightly has included srcset and sizes support for a few weeks – yesterday, John Schoenick (hero) landed picture support, too. It’s currently disabled by default (behind the dom.image.picture flag), but that should change soon. John is still aiming for on-by-default support in Firefox 33 (which, you may recall, ships on October 14th!).
Over on the Blink side of things, Yoav Weiss (who is definitely a hero) took sizes and w descriptors out from behind their experimental flag. Meaning that the features are on-by-default in Canary now, and will almost certainly be enabled for millions of Chrome users when version 38 ships on September 26th.
Heros, all of you.
See you in a couple of weeks!
