+	<div data-picture data-alt="A giant stone face at The Bayon temple in Angkor Thom, Cambodia">
+		<div data-src="small.jpg"></div>
+		<div data-src="medium.jpg" data-media="(min-width: 400px)"></div>
+
+		<!--[if (lt IE 9) & (!IEMobile)]>
+		    <div data-src="medium.jpg"></div>
+		<![endif]-->
+
+		<!-- Fallback content for non-JS browsers. Same img src as the initial, unqualified source element. -->
