<a href="viewpic.asp" target="_blank"> <img id="img_default" src="image/default.jpg" border="0" title="点击查看大图"> </a> <a href="javascript:changepic(1);"> <img id="img_1" src="image/1.jpg"/> </a> 
<a href="javascript:changepic(2);"> <img id="img_2" src="image/2.jpg"/> </a> 
<a href="javascript:changepic(3);"> <img id="img_3" src="image/3.jpg"/> </a> 
<a href="javascript:changepic(4);"> <img id="img_4" src="image/4.jpg"/> </a> 
...... 
<script type="text/javascript">
function changepic(id)
id=document.getElementById(id);
{
var oImg = document.getElementById("img_"+id).getAttribute("img_"+id); 
document.getElementById("img_default").setAttribute('src',oImg.getAttribute('src'));
