With a quick guess...I think he's talking something along these lines...although I haven't tested it...
Code:
<body>
<div style="text-align: center; padding: 0pt; margin: 0pt;">
<svg xmlns="http://www.w3.org/2000/svg" height="100%" preserveAspectRatio="xMidYMin meet" version="1.1" viewBox="0 0 600 600" width="100%" xmlns:xlink="http://www.w3.org/1999/xlink">
<image height="192" width="600" xlink:href="../Images/image1.gif" />
<image height="192" width="600" xlink:href="../Images/image2.gif" />
<image height="192" width="600" xlink:href="../Images/image3.gif" />
</svg>
</div>
</body>
