nivo slider - jquery slider - start off then turn on again

I have modified my wordpress home page to add a banner for new visitors.  

If the nivo slider is turned on, it is too distracting to read.  So I start with the nivo slider off by changing the javascript to:  manualAdvance:true,

So that works great.

But once someone closes the banner by clicking on it, I want to kick the animation back on.  How would I do that?  The live version of my code is found here:

Static version here:

<div id=tbl name=tbl style="overflow:hidden;display:block">
<table id="fullnb" border=0>
<tr><td><a href="javascript:sizeTbl('none')"><img src="http://www.rockthedeadline.com/images/Home-Page-Banner-white.jpg"></a></td></tr>
</table>
</div>
<script language="JavaScript" type="text/javascript">
<!--
function sizeTbl(h) {
  var tbl = document.getElementById('tbl');
  tbl.style.display = h;
}
// -->

I know I should be sticking something into the sizeTbl function to turn it back on, because that is the code that closes the banner, but I'm not sure what exactly.  

Thanks!
