That's not working, either.
If it makes any difference, my image is 429 x 750, so the only changes in Jon's code I pasted above is this line:
Code:
<image height="750" width="429" xlink:href="../Images/3.png"></image>
edit: With some creative editing, I managed to get the images 600x800 so it looks right. This all would have been much easier if the <center> tag wasn't deprecated in HTML.
