简单的三张图片自动切换的特效

首先这个问题是网上一搜一大堆的   但可惜我是做后台的   看那些CSS JS实在有点吃不消  而且现在最大的难点是这是修改的   原本是一张图片神马位置都固定好了  现在突然改变说什么得切换   设计的有事只能我这个做后台的躺枪咯   先贴上html页面的代码                  <div class="main_i">
                    <img class="slider2" alt="" src="Images/slider2.jpg" />
                    <div class="poplink">
                        <a class="pop1" href="Details.aspx?id=51"> </a> <a class="pop2" href="Details.aspx?id=54">
                             </a> <a class="pop3" href="Details.aspx?id=55"> </a> <a class="pop4" href="Details.aspx?id=53">
                                 </a> <a class="pop5" href="Details.aspx?id=52"> </a>
                    </div>
                </div>希望大家提供个简单一点的切换特效的代码JavaScriptHTMLCSS
