题目与上面的两篇文章有所重复，但是内容与上两篇上有所区别，本文中，实现的图片集展示的效果为：
1、详细图和缩略图的同步展示；
2、图片的自动播放；
3、显示图片的缩影图的焦点显示与别的图片的遮盖显示；
4、鼠标移动至详图显示图片控制控件。

具体效果图如下：

下面将我实现的代码贴出来，以供大家参考。
1、showimg.css

html, body{  
    height: 100%;  
    margin: 0;  
    padding: 0;  
    text-align: center;  
}  
#prev{  
    position: absolute;  
    top: 125px;  
    left: 0px;  
    width: 45px;  
    height: 50px;  
    background: url(../img/prev.png);  
}  
#next{  
    position: absolute;  
    top: 125px;  
    right: 0px;  
    width: 45px;  
    height: 50px;  
    background: url(../img/next.png);  
}  
#prev:hover,#next:hover{  
    cursor: pointer;  
}  
.detail-div{  
    position: relative;  
    display:inline-block;  
    padding:4px;  
    margin:0 0.5rem 1rem 0.5rem 1rem;  
    line-height:0;  
    -webkit-transition:background-color 0.1s ease-out;  
    -moz-transition:background-color 0.1s ease-out;  
    -o-transition:background-color 0.1s ease-out;  
    transition:background-color 0.1s ease-out;  
    -webkit-border-radius:6px;  
    -moz-border-radius:6px;  
    -ms-border-radius:6px;  
    -o-border-radius:6px;  
    border-radius:6px;  
}  
.thumb-div{  
    position: absolute;  
    bottom: -110px;  
    left: 4px;  
    background: #555;  
}  
.thumb{  
    margin-left: 7px;  
    margin-top: 5px;  
    margin-bottom: 5px;  
    float: left;  
    position: relative;  
}  
.thumb-img{  
    -webkit-border-radius:5px;  
    -moz-border-radius:5px;  
    -ms-border-radius:5px;  
    -o-border-radius:5px;  
    border-radius:5px  
}  
.thumb-active{  
    border: 2px solid #fff;  
    -webkit-border-radius:5px;  
    -moz-border-radius:5px;  
    -ms-border-radius:5px;  
    -o-border-radius:5px;  
    border-radius:5px;  
    height: 100px;  
}  
.thumb-modal{  
    background: #141414;  
    opacity: 0.5;  
    filter:alpha(opacity=50);  
    position: absolute;  
    left: 0px;  
    bottom: 2px;  
    -webkit-border-radius:5px;  
    -moz-border-radius:5px;  
    -ms-border-radius:5px;  
    -o-border-radius:5px;  
    border-radius:5px;  
}  
.thumb-modal-hide{  
    display: none;  
}

2、juqery.showimg.js

(function($){  
    $.fn.showImg = function(options){  
        var defaults = {};  
        var options = $.extend(defaults, options);  
        var container=$(this);  
        var imgUrls = options.imgUrls;  
        var width = options.width,height = options.height,thumbHeight = options.thumbHeight;  
        var autoPlay = options.autoplay;  
  
        container.css("width",width+"px");  
  
        var imgIndex = 1,length = imgUrls.length;  
        var play;  
  
        /** 
         * 图片详情 
         */  
        var detailDiv = $("<div></div>").addClass("detail-div").appendTo(container);  
  
        var ctrlDiv = $("<div></div>").appendTo(detailDiv).hide();  
        var prevA = $("<a></a>").attr("id","prev").appendTo(ctrlDiv).hide(),  
            nextA = $("<a></a>").attr("id","next").appendTo(ctrlDiv);  
  
        $(".detail-div").live("mouseenter",function(){

        });

        addThumbImgs();  
  
        prevA.on("click",function(){

        });  
        nextA.on("click",function(){
