  1.   

    <body leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" onLoad="window.resizeTo(640,480)">
    <img src="pic/20041228224912.gif" width="640" height="480"> 
    </body>通通搞成 640*480 了。
      

  2.   

    <script language="javascript">
    var img=null;
    function zhiin(url)
    {
    if(img) img.removeNode(true);
    img=document.createElement("img");
    img.style.position="absolute";
    img.style.visibility="hidden";
    img.attachEvent("onreadystatechange",orsc);
    img.attachEvent("onerror",oe);
    document.body.insertAdjacentElement("beforeend",img);
    img.src=url;
    }
    function oe()
    {
    alert("cant load img");
    }
    function orsc()
    {
    if(img.readyState!="complete")return false;
    oWin = window.open("about:blank","","width="+img.offsetWidth+",height="+img.offsetHeight);
    oWin.document.write("<html><head><title>zhiin.net</title><style>body{margin:0px}</style></head><body><img src="+img.src+"></body></html>") ;}
    </script><button onclick="zhiin('http://community.csdn.net/ADV/Images/csdn120x360.GIF')">open image</button>
      

  3.   

    <body>
    <img src="61.jpg" name="aaa" width="800" height="600">
    <script language="JavaScript">
    window.resizeTo(aaa.width,aaa.height) 
    </script>
    </body>
