我怎样才能缩短它以使其全部适合一个功能。我有一个工作图像库，当单击具有类 a 的图像时，类 bigimg 中的图像更改为选定的图像。我可能已经做了很长的更改图像的工作，但最多只有十几个。

顺便说一句，我将托管我的图片，这些图片仅用于我的测试

HTML/jQuery

<div id="galleryholder">

            <div id="largeimg" class="center">
                <img class="bigimg" src="http://1.bp.blogspot.com/-BNkayp7vphQ/UEmx3WTwe1I/AAAAAAAAELg/eHu4hWtoXbk/s1600/desktop-wallpaper-29.jpg">
            </div>

            <div id="reel">
                <a href=""><img class="a" src="http://wallpaperstate.org/wp-content/gallery/ca_home/hd-wallpaper-30.jpg"></a>
                <a href="#"><img class="b" src="http://1.bp.blogspot.com/-BNkayp7vphQ/UEmx3WTwe1I/AAAAAAAAELg/eHu4hWtoXbk/s1600/desktop-wallpaper-29.jpg"></a>
                <a href="#"><img class="c" src="http://1.bp.blogspot.com/-BNkayp7vphQ/UEmx3WTwe1I/AAAAAAAAELg/eHu4hWtoXbk/s1600/desktop-wallpaper-29.jpg"></a>
            </div>

                <script>
                $(function() {

                  $('.a').click(function(){
                    $(".bigimg").attr('src',"http://wallpaperstate.org/wp-content/gallery/ca_home/hd-wallpaper-30.jpg");
                    return false;
                  });
                });


                $(function() {
                  $('.b').click(function(){
                    $(".bigimg").attr('src',"http://1.bp.blogspot.com/-BNkayp7vphQ/UEmx3WTwe1I/AAAAAAAAELg/eHu4hWtoXbk/s1600/desktop-wallpaper-29.jpg");
                    return false;
                  });
                });
                </script>

        </div>

src从单击的图像中动态拉取：

var $big = $(".bigimg");

$('#reel img').click(function () {
    $big.attr('src', this.src);
    return false;
});
