单击图像周围的空白区域时，Javascript幻灯片显示会出现问题

所以我得到了这个幻灯片代码，当你点击一个图像时，它会消失在另一个图像中。但是，如果，例如，有一个垂直方向的图像，其右侧有空白，如果单击该空间，整个幻灯片显示就会出现小故障

这是我的网站，您可以在这里进行测试：

代码：

$(document).ready(function() {
$.fn.nextOrFirst = function (selector) {
    var next = this.next(selector);
    return (next.length) ? next : this.prevAll(selector).last();
};
$("#cf2 img").click(function() {
    $(this)
    .removeClass('visible')
    .nextOrFirst()
    .addClass('visible');
  });
});

#cf2 {
  position:relative;
  height:281px;
  width:450px;
  margin:0 auto;
}
#cf2 img {
  position:absolute;
  left:0;
  max-height: 600px;
  max-width: 600px;
  opacity: 0;

  -moz-transition: opacity 1s ease-in-out;
  -o-transition: opacity 1s ease-in-out;

}

#cf2 img.visible {
  opacity: 1;
  z-index: 1;

如果我理解的话，这里的问题是当您在图像外部但在上一张图像的正方形内部单击时，幻灯片不会改变

这种方法不改变YoutJavaScript，而是改变html和一些选择器

在下面的示例中，我将每个

试图找到故障，但什么也找不到。你能更具体地说明这个小故障是如何发生的吗？页面冻结了？选择突出显示棒？一群蝗虫入侵你的家？（这在我身上时有发生）我明白了。但是非常感谢你的帮助！啊!！这很有道理。非常感谢，工作做得很好。：）显然，Java还是新手！
