Quick jQuery question - I need the popup to load when the page loads

Ok so I've been following this tutorial - http://yensdesign.com/2008/09/how-to-create-a-stunning-and-smooth-popup-using-jquery/
to get a popup to fade in on my site.

But that tutorial has the popup fade in after you click a button. I want the popup to fade in as soon as the page loads. There's got to be a quick fix to this.
I think this is the code that needs editing:

//CONTROLLING EVENTS IN jQuery
$(document).ready(function(){
	
	//LOADING POPUP
	//Click the button event!
	      $("#button").load(function(){
		//centering with css
		centerPopup();
		//load popup
		$loadPopup();
	});

Code (markup):

Can I get some help please?

 

.load is an event handler. you should be ok by removing everything within the ready except for the

$(document).ready(function() {
    centerPopup();
    $loadPopup();
});

Code (javascript):

of course, since i don't know what lies beyond the 2 functions you call, i can't confirm it will work or not.

 

Perfect, thanks a lot!
