I still have 3.6 version and have used this code in one of the boxes:
<a href=?
http://www.portaleducation.com.au? rel="nofollow" target="_blank"><img src="http://www.podiatry-arena.com/images/Bowles.swf" width="120" height="450" alt="Portal Education" ></a>
Link doesn't work and image doesn't show up (its in the right place) - anyone point out what I not done right?
(the iframe code from Amazon affiliate program works fine in other boxes)
