图片自动按比例缩小代码（防止页面被图片撑破）

<div id=article><img height="800" alt="" width="1280" src="/down/js/images/12498880470.jpg" /></div><script type="text/javascript" >//缩放图片到合适大小function ResizeImages(){   var myimg,oldwidth,oldheight;   var maxwidth=550;   var maxheight=880   var imgs = document.getElementById('article').getElementsByTagName('img');   //如果你定义的id不是article，请修改此处   for(i=0;i<imgs.length;i++){     myimg = imgs[i];     if(myimg.width > myimg.height)     {         if(myimg.width > maxwidth)         {            oldwidth = myimg.width;            myimg.height = myimg.height * (maxwidth/oldwidth);            myimg.width = maxwidth;         }     }else{         if(myimg.height > maxheight)         {            oldheight = myimg.height;            myimg.width = myimg.width * (maxheight/oldheight);            myimg.height = maxheight;         }     }   }}//缩放图片到合适大小ResizeImages();</script><p>查找更多代码，请访问：<a href="http://www.lanrentuku.com" target="_blank">懒人图库</a></p>
