换图做个测试：参考：
<div align=center style="overfow: hidden; width: 100px; height: 100px">
<img src="3.jpg" width="100" height="100" border="0" onmouseover="show(this)" onmouseout="hide(this)">
</div>
<div align=center style="overfow: hidden; width: 100px; height: 100px">
<img src="1.jpg" width="100" height="100" border="0" onmouseover="show(this)" onmouseout="hide(this)">
</div>
<div align=center style="overfow: hidden; width: 100px; height: 100px">
<img src="2.jpg" width="100" height="100" border="0" onmouseover="show(this)" onmouseout="hide(this)">
</div>
<div id="enlarge_images" style="position: absolute; z-index:2"></div>
<SCRIPT>
function show(_this) {
document.getElementById("enlarge_images").innerHTML = "<img src='" + _this.src + "' >";
}
function hide(_this) {
document.getElementById("enlarge_images").innerHTML = "";
}
function move_layer(event){
event = event || window.event;
enlarge_images.style.left=event.clientX+document.body.scrollLeft+10;
enlarge_images.style.top=event.clientY+document.body.scrollTop+10;
}
document.onmousemove =move_layer;
</SCRIPT>
