脚本说明:

第一步：把如下代码加入<body>区域中
<script type="text/javascript">
// 7 variables to control behavior
    var Car_Image_Width=140;
    var Car_Image_Height=225;
    var Car_Border=true;        // true or false
    var Car_Border_Color="white";
    var Car_Speed=4;
    var Car_Direction=true;        // true or false
    var Car_NoOfSides=8;        // must be 4, 6, 8 or 12

/* array to specify images and optional links.
    For 4 sided carousel specify at least 2 images
    For 6 sided carousel specify at least 3
    For 8 sided carousel specify at least 4
    For 12 sided carousel specify at least 6
If Link is not needed keep it ""

</script>
<div id="Carousel" style="position:relative">
   <img src="200310171/placeholder.gif" width="371" height="225">

第二步：把<body>中的内容改为：
<body onload="Carousel()">
