从图像的右中心使用 jquery 的图像幻灯片

我正在制作图像的幻灯片，我正在尝试使用本教程：http : //www.slidesjs.com/

我下载了 zip 文件并开始使用它，它工作正常。我唯一尝试但无法使其工作的是右下角的那四个点，我希望它们位于实际图像上，但位于边界线上的右中心。

一个例子是这样的：https : //s2.postimg.org/ochp3uevt/scroller.png

如果您查看上面的图像（未显示完整图像），则所有点都是垂直的而不是水平的，并且位于该图像的右侧中心。我也想做类似的事情。这有可能做到吗？

我尝试使用margin-top但它对我不起作用。

更新：-

有一个 CSS 从中出现了四个点的图像，我已经修改了它以包含 margin-top 但它没有用：

.slidesjs-pagination li a {
  display: block;
  width: 13px;
  height: 0;
  padding-top: 13px;
  background-image: url("https://s16.postimg.org/pt4k43i9x/pagination.png");
  background-position: 0 0;
  float: left;
  <!-- added by me-->
  margin-top: -50px; 
}

这是完整的 HTML 代码：

你想菜单绝对定位到右侧一个值right，将创建菜单和右侧之间的空间，将其移动到中央，然后非float对li的。

#slides {
  position: relative;
}
#slides .slidesjs-pagination {
  position: absolute;
  top: 50%; right: 1em;
  transform: translateY(-50%);
  z-index: 9999;
}
#slides .slidesjs-pagination li {
  float: none;
}
