I am new to learning JavaScript and I could really use some help. My boss insisted on a carousel for his homepage, so I watched a YouTube video on how to create one with JavaScript. There are a few things I want to change, however and I can't figure it out.

I pasted my code below. I really want it so that if the user HOVERS over the carousel it begins to twirl, not on the page load. How can I fix this?
Another question is when I put it on the page, it keep bleeding over the container. Is there a way I can fix this in the JS code?

I really appreciate the help. I did try to fox this myself before the post but I am too new to this to figure it out and I am really stuck.

Code:
var pictures = new Array('ANGELIQUE.jpg','AVANTI.jpg','CHALET.jpg','Chloe.jpg','Danube.jpg','Gallery.jpg','METROPOLIS.jpg','Ovation.jpg','PANACHE.jpg','Sentiments.jpg','Sorbet.jpg','St. Laurent.jpg','VeineDor.jpg','XVI.jpg');
var functions = new Array ('func1()','func2()','func3()','func4()','func5()','func6()','func7()','func8()','func9()','func10()','func11()','func12()','func13()','func14()');
var items = pictures.length;
var angles = new Array(items);
var images = new Array(items);
var rx = 250;
var ry = 10;
var cx = 0;
var cy = 0;

function itemSize()
{
	for(var i = 0; i < items; i++)
	{
		images[i] = new Image();
		images[i].src = pictures[i];
	}
	initCar();
}

function initCar()
{
	var content = document.getElementById('content');
	for(var i = 0; i < items; i++)
	{

		angles[i] = ((Math.PI * 2) / items) * i;
		var xpos = Math.cos(angles[i]) * rx;
		var ypos = Math.sin(angles[i]) * ry;
		var obj = newObj(i, xpos, ypos, parseInt(ypos), pictures[i]);
		content.innerHTML += obj;	
	}	
	mouseOver('rotateCar()' , 18);
}

		obj.style.left = xpos + 'px';
		obj.style.top = ypos + 'px';
		obj.style.zIndex = parseInt(ypos);
		
		var objImg = document.getElementById('img' + i);
		var delta = (ypos - cy + ry) / (2 * ry);
