3.页面调用：

<script type="text/javascript" src="js/jquery-1.9.1.js"></script>

<script type="text/javascript" src="js/jquery.imgScroll.js"></script>(上面那个js)

$('.lbCon .lbBox .lbList').imgScroll({

        firstDiv: '.lbCon .lbBox',

        scrollBox: '.lbCon .lbBox .lbList',

        scrollImgBox: '.lbCon .lbBox ul',

        botPrev: '.lbCon .lbPrev',

        botNext: '.lbCon .lbNext',

        changeType: "slide",

        thumbNowClass: 'on',

        thumbOverEvent: true,

        changeTime: 5000,

        ImgBoxMar: 0,

        flag: false

    })

4.至于鼠标滑过 显示左右按钮,可以这么写（思路:css默认隐藏左右按钮，鼠标滑过显示左右按钮，划出隐藏，需要引入jquery.js）

$(function(){

   $(".wj_jdt_1").bind("onmouseover",function(){

       $(".ctr_btn").show()

   }).bind("onmouseout",function(){

       $(".ctr_btn").hide()

   })

})

大体是这么个意思，至于怎么延伸在你
