FlashPanos

This one must be easy, but I'm more interested in using the player than programming it.
The only thing I want is to make a "Full Screen" button (image, hotspot or whatever) somewhere on a web page OUTSIDE the panorama window.

Here is some of my superstandard javascript:

// = 6)
{
var so = new SWFObject("krpano.swf", "krpanoSWFObject", "716px", "390px", "9.0.28","#000000");
so.addParam("allowFullScreen","true")
so.addVariable("pano", "scrn_piccadilly_circus_01.xml");
so.useExpressInstall("./swfobject/expressinstall.swf");
so.setAttribute("xiRedirectUrl", window.location);
if ( so.write("krpano") ) { var mousewheelfixes = new SWFkrpanoMouseWheel(so); }
...
and so on.

I guess it is a line or two of Javascript I need.
You may take a look at http://sphaerama.com/panoramas/!pg_piccadilly_circus_01.htm to see what I don't want. All other pages on the site still runs in Java!

Thanks!
