</html><script >

function save(){
var index=1;
for(var i=1; i<=4;i++){
for(var j= 1;j<=4;j++){
document.getElementById("div"+j).style.display="none";
}
if(i==index){
document.getElementById("div"+i).style.display="inline";

  1.   

    <body  onload="save()"><div  id="div1"style="  display:none"><img src="图片资源/1.jpg" width="200" height="150" alt="1" /></div>
    <div id="div2" style=" display:none"><img src="图片资源/2.jpg" width="200" height="150" alt="2" /></div>
    <div id="div3"  style=" display:none"><img src="图片资源/3.jpg" width="200" height="150" alt="3" /></div>
    <div id="div4"  style=" display:none"><img src="图片资源/4.jpg" width="200" height="150" alt="4" /></div>
    </body>
    </html><script >    var index = 1,delay=3000///修改切换间隔，单位为ms
        function save() {
            for (var j = 1; j <= 4; j++) {
                document.getElementById("div" + j).style.display = "none";
            }
            document.getElementById("div" + index).style.display = "inline";
            index++;
            if (index > 4) index = 1;
        }
        setInterval(save, delay);
    </script>
      

  2.   

    实现图片轮播，带轮播效果。
    /**************************************************
    名称: 图片轮播类
    创建时间: 2007-11-12
    示例:
    页面中已经存在名为imgPlayer(或者别的ID也行)的节点.
    PImgPlayer.addItem( "test", "http://www.pomoho.com", "http://static.pomoho.com/static/samesong/images/logo5.jpg");
    PImgPlayer.addItem( "test2", "http://www.pomoho.com.cn", "http://static.pomoho.com/static/samesong/images/logo4.jpg");
    PImgPlayer.addItem( "test3", "http://www.pomoho.com.cn", "http://static.pomoho.com/static/samesong/images/logo3.jpg");
    PImgPlayer.init( "imgPlayer", 200, 230 );
    备注:
    适用于一个页面只有一个图片轮播的地方.
