<script type="text/javascript">

            $(document).ready(function() {

                $(".paging").show();

                $(".paging a:first").addClass("active");

                var imageWidth = $(".window").width();

                var imageSum = $(".image_reel img").size();

                var imageReelWidth = imageWidth * imageSum;

                $(".image_reel").css({

                    'width' : imageReelWidth

                });

                var rotate = function() {

                    var triggerID = $active.attr("rel") - 1;

                    var image_reelPosition = triggerID * imageWidth;

                    $(".paging a").removeClass('active');

                    $active.addClass('active');

                    $(".image_reel").animate({

                        left : -image_reelPosition

                    }, 500);

                };

                var rotateSwitch = function() {

                    play = setInterval(function() {

                        $active = $('.paging a.active').next();

                        if($active.length === 0) {

                            $active = $('.paging a:first');

                        }

                        rotate();

                    }, 3000);

                };

                rotateSwitch();

                $(".image_reel a").hover(function() {

                    clearInterval(play);

                }, function() {

                    rotateSwitch();

                });

                $(".paging a").click(function() {

                    $active = $(this);

                    clearInterval(play);

                    rotate();

                    return false;

                });
