jQuery代码：

$(function() {
                var index = 0;
                var length = $("#img img").length;
                var i = 1;

                //关键函数：通过控制i ，来显示图片
                function showImg(i) {
                    $("#img img")
                        .eq(i).stop(true, true).fadeIn(800)
                        .siblings("img").hide();
                    $("#btns li")
                        .eq(i).addClass("hov")
                        .siblings().removeClass("hov");
                }

                function slideNext() {
                    if(index >= 0 && index < length - 1) {
                        ++index;
                        showImg(index);
                    } else {

                            index = 0;
                            aniPx = (length - 5) * 142 + 'px'; //所有图片数 - 可见图片数 * 每张的距离 = 最后一张滚动到第一张的距离
                            $("#cSlideUl ul").animate({
                                "left": "+=" + aniPx

                        return false;
                    }
                    if(i < 0 || i > length - 5) {
                        return false;
                    }
                    $("#cSlideUl ul").animate({
                        "left": "-=142px"
                    }, 200)
                    i++;
                }

                function slideprev() {
                    if(index >= 1) {
                        --index;
                        showImg(index);
                    }
                    if(i < 2 || i > length + 5) {
                        return false;
                    }
                    $("#cSlideUl ul").animate({
                        "left": "+=142px"
                    }, 200)
                    i--;
                }
                $("#img img").eq(0).show();
                $("#btns li").eq(0).addClass("hov");
                $("#btns tt").each(function(e) {
                    var str = (e + 1) + "/" + length;
                    $(this).html(str)
                })

                $(".picSildeRight,#next").click(function() {
                    slideNext();
                })
                $(".picSildeLeft,#prev").click(function() {
                    slideprev();
                })
                $("#btns li").click(function() {
                    index = $("#btns li").index(this);
                    showImg(index);
                });
                $("#next,#prev").hover(function() {
                    $(this).children("a").fadeIn();
                }, function() {
                    $(this).children("a").fadeOut();
                })
            })

如果感觉还不错，麻烦给个小心心。
