Проблема с JavaScript

JavaScript:
<script type="text/javascript">
function over(file_name)
{
img = document.createElement('div');
document.body.appendChild(img);
img.innerHTML = '<img src='+file_name+' />';
img.style.position = 'absolute';
img.style.background = '#FFFFFF';
img.style.border = 'solid 1px #ccc';
img.style.padding = '4px';
move();
}
function move(e)
{
e = e || window.event
if (e.pageX == null && e.clientX != null )
{
var html = document.documentElement
var body = document.body
e.pageX = e.clientX + (html && html.scrollLeft || body && body.scrollLeft || 0) - (html.clientLeft || 0)
e.pageY = e.clientY + (html && html.scrollTop || body && body.scrollTop || 0) - (html.clientTop || 0)
}
img.style.left = e.pageX + 15 + 'px';
img.style.top = e.pageY + 15 + 'px';
}
function out()
{
document.body.removeChild(img);
}
</script>
