Hi

I have this Ajax slide effect that I want to use on my website. I have about six images that I use, but I would like to set it up if possible so that each time a person comes to the page the images are loaded at random so a different one appears as the first one each time.

As I know very little about Ajax or javascript I thought I would post to see if somebody could help.


Here is the code.

Code:
window.addEventListener?window.addEventListener('load',so_init,false):window.attachEvent('onload',so_init);
var d=document, imgs = new Array(), zInterval = null, current=0, pause=false;

function so_init()
{
if(!d.getElementById || !d.createElement)return;
	css = d.createElement('link');
	css.setAttribute('href','css/slide.css');
	css.setAttribute('rel','stylesheet');
	css.setAttribute('type','text/css');
	d.getElementsByTagName('head')[0].appendChild(css);

	imgs = d.getElementById('rotator').getElementsByTagName('img');
	for(i=1;i<imgs.length;i++) imgs[i].xOpacity = 0;
	imgs[0].style.display = 'block';
	imgs[0].xOpacity = .99;
	
	setTimeout(so_xfade,11000);

}
function so_xfade()
{
	cOpacity = imgs[current].xOpacity;
	nIndex = imgs[current+1]?current+1:0;
	nOpacity = imgs[nIndex].xOpacity;

	cOpacity-=.05;
	nOpacity+=.05;

	imgs[nIndex].style.display = 'block';
	imgs[current].xOpacity = cOpacity;
	imgs[nIndex].xOpacity = nOpacity;

	setOpacity(imgs[current]);
	setOpacity(imgs[nIndex]);

	if(cOpacity<=0)
	{
		imgs[current].style.display = 'none';
		current = nIndex;
		setTimeout(so_xfade,11000);
	}
	else
	{
		setTimeout(so_xfade,50);
	}

	function setOpacity(obj)
	{
	if(obj.xOpacity>.99)
		{
			obj.xOpacity = .99;
			return;
		}
		obj.style.opacity = obj.xOpacity;
		obj.style.MozOpacity = obj.xOpacity;
		obj.style.filter = 'alpha(opacity=' + (obj.xOpacity*100) + ')';
	}
}
If anybody could help then that would be great. If not if anybody could point me in the direction of a slide effect slideshow that can load images at random then that would be good too although I do like this script for its ease of set up.
