Actually, it's easier to do this with CSS. Use something like this:
Float image left:
<img src="marketo.jpg" style="float:left">
Float image right:
<img src="marketo.jpg" style="float:right">
Add padding to image:
<img src="marketo.jpg" style="float:left;padding:3px">
In the CSS property inspector, add a value of float and specify if you want it right/left.
