dreamweaver网页的JS里怎么设置让图片自动缩小至规定的尺寸？

<div id="imgADPlayer" style="display: block; width: 320px; height: 240px; position: relative; overflow: hidden;"><a href="http://www.anyilvhejin.com/ch/index.asp#" title="1" target="_blank" style="display: block; text-decoration: none; width: 320px; height: 240px; background-image: url(http://www.anyilvhejin.com/ch/img/3.jpg); background-position: 50% 50%; background-repeat: no-repeat no-repeat; "></a>
<ul style="margin:0; width:320px; position:absolute; right:-1px; FILTER:Alpha(Opacity=30,FinishOpacity=90, Style=1); overflow: hidden; bottom:-1px; height:16px; border-right:0px solid #002342; z-index: 999; background-image: url(img/3.jpg); layer-background-image: url(img/3.jpg); border: 1px none #000000;">
<li style="margin:0;list-style-type: none; margin:0;padding:0; float:right;"><span onmouseover="PImgPlayer.mouseOver(this);" onmouseout="PImgPlayer.mouseOut(this);" style="clear:both; display:block; width:23px;line-height:18px; font-size:12px; FONT-FAMILY:'宋体'; opacity: 0.6;border:1px solid #002342;border-right:0;border-bottom:0;color:#ffffff;text-align:center; cursor:pointer; background:#ff0000;" onclick="PImgPlayer.play(4);return false;" herf="javascript:;" title="1">5</span></li>

</div>

你这是上传服务器之后又复制下来的吧？

<script language="JavaScript">

var flag=false;
function DrawImage(ImgD){
var image=new Image();
image.src=ImgD.src;
if(image.width>0 && image.height>0){
flag=true;
if(image.width/image.height>= 200/200){
if(image.width>200){
ImgD.width=200;
ImgD.height=(image.height*200)/image.width;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}

}
else{
if(image.height>200){
ImgD.height=200;
ImgD.width=(image.width*200)/image.height;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}

}
}
}

</script>
上面这段写在 head里

下面的代码写到body里：
<img src=# onload=javascript:DrawImage(this); >
