一般不建议使用expression，因为expression对浏览器资源要求比较 高。之前在做一个图集风格的时候在网上看到了一些用js控制图片的例子，我就分享一下给大家！

<script language="javascript">  
     function checkImg(mypic){  
     var xw=720;  
     var width = bigimg.width;  
     if (width > xw ) bigimg.width = xw;  
}  
</script>  
 
<img  id="bigimg" onload="checkImg(this)" src=&#39;/uploads/allimg/100701/co100F1194604-0.jpg&#39;  width=&#39;1023&#39;  alt=&#39;&#39; />
