Going with your angle for a simple example with two sizes: >> >> <picture alt="alternative text" src="default.jpg"> >> <source href="large.jpg" media="min-width:700px" /> >> <img alt="alternative text" src="default.jpg" /> >> </picture> > > A new element may be an opportunity to get the "alt" right, i.e. in element's body, not flattened in an attribute. Is there a reason for this? I think this is more confusing than everything else. And, an alternative text shouldn't have markup. Alternative text should be all for accessibility. What you thinking about might be the title-attribute. But I'm totally against this approach to do this inside the element w/o attribute. And I think screenreader won't be happy with that, too? (not sure about that). > <picture> > <source href="wide.jpg" media="orientation: landscape" /> > <source href="narrow.jpg" media="orientation: portrait" /> > > <img alt="alternative text" src="default.jpg" /> > > alternative <em>text</em> > </picture> > > > For DPI/filesize selection I'd prefer something simpler: > > <picture src="large.jpg" lowsrc="small.jpg"> <!-- or <source high-dpi-href="" or such> --> > alternative <em>text</em> > </picture> > > as it's going to be very hard to write a media query that takes into account various screen sizes, DPI and bandwidth/metering at the same time. This is similar to my approach using the common img-tag. In that case we don't need a new element. But as you've said many people (also here) find it a bit hard to write. Imagine using 6 different image sizes in that case? You can read arguments some mails before on my approach. > When browser has a high-quality image the cached already, but media query for "network-connection: gprs" matches, it would be shame to force it to switch to a lousy image. > > -- > regards, Kornel Lesi?ski -Anselm
