话不多说，先上大致效果：

本着程序员的开源精神，代码奉上：

注意：

1. 类名不要随意更改（否则插件里面的也要更改），替换图片地址即可。
2. data-setting属性记得按照以上格式设置，不然可能报错

script代码:

<script src="jquery.js"></script>
<script src="jquery.pokerCarousel.js"></script>
<script>
pokerCaroursel.init($('.pokerCaroursel'))
</script>	

注意：
要记得先引入jquery.js文件（可去官网下载：https://jquery.com/download/），再引入jquery.pokerCarousel.js文件
