*rachelreveley*: There’s a lot of conversation around that going on as we speak. It could go either way, really. `picture` wouldn’t replace common `img` tags everywhere; it would mostly be used for large hero images, like the ones seen on Apple.com. The general use would be only a few per page — and even then, having all that consolidated in the head could get pretty unwieldy. On the other hand, it would mean just as much markup down in the `body` otherwise. Matt Wilcox is a big proponant of the `head`-based approach — his “post”:http://mattwilcox.net/archive/entry/id/1091/ on the subject is well worth a read.
The important thing is that we have a chance to discuss these kinds of potential improvements in a productive, meaningful way. If the WHATWG proposal were pushed through by a few key players, we may never have a chance to put these kinds of suggestions to use.
