//Generate transition CSS (transition=0 to 23)
document.write('<STYLE TYPE="text/css">.imgTrans{ filter:revealTrans(duration=0.4,transition=12) }</STYLE>');

//Uncomment the next line for fading rollovers instead of dissolving:
//document.write('<STYLE TYPE="text/css">.imgTrans{ filter:blendTrans(duration=0.4) }</STYLE>');

var onImages=new Array();
function Rollover(imgName, imgSrc)
{
	onImages[imgName] = new Image();
	onImages[imgName].src = imgSrc;
}

function turnOn(imgName){

if(document.images[imgName].filters != null)
		document.images[imgName].filters[0].apply();
	document.images[imgName].offSrc = document.images[imgName].src;
	document.images[imgName].src    = onImages[imgName].src;
	if(document.images[imgName].filters != null)
		document.images[imgName].filters[0].play();
}

	if(document.images[imgName].filters != null)

//Specify name of participating images, plus paths to their onMouseover replacements:
Rollover("name you want to appear when the mouse goes over pic",  "name of pic.gif");
Rollover("name you want to appear when the mouse goes over the pic", "name of pic.gif");
