<script language="javascript">
function showPic(e,sUrl){
var x,y
x = e.clientX
y = e.clientY
document.getElementById("Layer1").style.left = x+2+'px'
document.getElementById("Layer1").style.top = y+2+'px'
document.getElementById("Layer1").innerHTML = "
<img border='0' src=\"" + sUrl + "\">"
document.getElementById("Layer1").style.display = ""
}
3、然后输入代码：
function hiddenPic(){
document.getElementById("Layer1").innerHTML = ""
document.getElementById("Layer1").style.display = "none"

</div>
<img src="http://avatar.profile.csdn.net/D/8/D/2_dean8828.jpg" onmouseout="hiddenPic()"
onmousemove="showPic(this.src)" />
5、然后输入代码：
<p>
<a href="" onmouseout="hiddenPic()" onmousemove="showPic(event,'http://avatar.profile.csdn.net/D/8/D/2_dean8828.jpg')">
