Here it is:
Code:
<div>
<svg xmlns="http://www.w3.org/2000/svg" height="100%" preserveAspectRatio="xMidYMid meet" version="1.1" viewBox="0 0 783 1200" width="100%" xmlns:xlink="http://www.w3.org/1999/xlink">
<image height="1200" width="783" xlink:href="../Images/cover.jpg"></image>
</svg>
</div>
In this example, the cover is 1200x783 pixels.
