Regarding image center there is currently bug setting display: block on the image, also "margin-left: auto; margin-right: auto;" doesn't seems to work in IE and Chrome so I'm not sure how it should work.
The simplest way to achieve what you want is:
<div style="text-align:center;"><img class="center" src="https://www.google.com/images/srpr/logo1w.png" alt="Product Image" /></div> Regarding the "width: 120px;" issue, this is a bug, though this seems to work only in IE.. not sure why is that, need to check it.
