Full IMG background on DIV

This Fiddle fills a IMG inside a DIV, without using it as background-image, without white-spaces, retaining aspect ratio and scaling it.

HTML

<!-- Based on the example found in this site: http://css-tricks.com/perfect-full-page-background-image/ -->
<div class="container">
    <img src="https://www.gravatar.com/avatar/9bc69b8d4bbf5ae2d238caf101d667e0?s=80" alt="Mandarinazul" width="630" height="337" />
</div>
<p class="resized"></p>

CSS

body, html {
	width: 100%;
	margin: 0;
	padding: 0;
	height: 100%;
}
.container {
	width: 60%;
	height: 70%;
	border: dashed 2px #f7860b;
	overflow: hidden;
