The good thing on the picture element is that we have the possibility to serve other image-crops and with that the meaning could change so we could update the alt-attribute in the tag for every source-element. I do know this is a very special case but valid: An image displayed for a desktop while a monochrome display will get an drawing / shape-image instead. This has the very much same meaning but a different content and has to have a different description in alt-attribute IMO. Another thing is: We do not have any graphic editor to do such things you have described yet. So you have to write this on your own along with SVG polyfills etc. This is a valid solution but won't work for the masses of developers. Please, always think of the millions of HTML-developers who only want to do a normal cool website using responsive images. Thanks! -Anselm Am 16.05.2012 um 03:23 schrieb Aldrik Dunbar: > Hi there, > > Adding a new *presentational* attribute/element for adaptive/responsive > images makes no sense and is not required.
