Fancybox不会进入Fancybox窗口

Question

我正在尝试制作图像＆＃34; pop＆＃34;同样，但没有任何工作。这是我在Head标签之间插入的代码：

                overlay : {
                    css : {

                }

            afterLoad : function() {
                this.title = 'Image ' + (this.index + 1) + ' of ' + this.group.length + (this.title ? ' - ' + this.title : '');

            .fancybox({

                    thumbs : {
                        width: 75,
                        height: 50
                    }
                }
            });
        });


    });
</script>

这是我用于图像的示例代码，该代码用于弹出Fancybox窗口，插入Body标签内的某处：

<a class="fancybox" href="images/thumbnail_chry_bw.png" data-fancybox-group="gallery" title="Lorem ipsum dolor sit amet"><img src="images/thumbnail_chry_bw.png" alt="" /></a>

它们的来源正确，因为包含jquery文件（lib）和（source）的两个文件夹与包含此处提到的代码的HTML文件位于同一文件夹中。我不知道自己做错了什么，因为网络开发不是我的强项。但是，我所拥有的几乎是Head标签内的<script>代码和Body标签内的图像链接。
