漂浮图片HTML：
<div id="img" style="z-index: 10; position: absolute; margin: 0px; width: 180px;
height: 100px; top: 157px; left: 180px">
<div>
<a id="imgUrl" href="<%= strUrls%>" target="_blank">
<img id="showImg" src="../windowPic/<%= filePath%>" width="180" height="100" border="0"
name="pic" onclick="isURL();" style="filter: revealtrans(duration=2.0,transition=19)">
</a>
</div>
<iframe src="javascript:false" style="z-index: -1; position: absolute; filter: progid:DXImageTransform.Microsoft.Alpha(style=0,opacity=0);
width: 180px; height: 100px; visibility: inherit; top: 0px; left: 0px; border: 0px;">
</iframe>
</div>
改动：注释了“移动”、“关闭”功能，将右上角20×20像素设置成关闭按钮区域，鼠标到该区域自动出"关闭"title，点击则关闭随机浮动图片。（用到了jQuery）
使用iframe使浮动图片显示在顶层。
使用示例：
<script type="text/javascript">
var ad1=new AdMove("img",true);
ad1.Run();
</script>
右侧上下浮动窗口JS：
var lastScrollY=0;
function heartBeat(){
var diffY;
if (document.documentElement && document.documentElement.scrollTop){
diffY = document.documentElement.scrollTop;
}
else if (document.body){
diffY = document.body.scrollTop;
}else{
/*Netscape stuff*/
}
percent=.1*(diffY-lastScrollY);
if(percent>0)percent=Math.ceil(percent);
else percent=Math.floor(percent);
document.getElementById("track").style.top=parseInt(document.getElementById("track").style.top)+percent+"px";
lastScrollY=lastScrollY+percent;
} window.setInterval(heartBeat,40);
右侧浮动窗口HTML就不贴出了，就是一DIV，ID为“track”，基本CSS为“z-index: 6; position: absolute; height: 150px; _width: 210px;right: 0px; top: 242px;”。
