　　分享一个代码简洁的Jquery slide show 图片切换，网上有很多基于Jquery的slide show，效果很漂亮、功能也很全，但是如果要应用某种效果，就非得导入某个插件，而这些文件通常都不会太小，为个一个slide show就导入一个文件，觉得有点不值，所以自己写了一个，分享出来，有用到的同学可以拿过去用用。

　　发现问题的同学请随便嘀咕一下，只言片语也是对我的帮助，谢谢.....

　　烈火提示：代码中为了演示方便，没有使用图片，如果您打算用于图片切换，可自行修改。

　　为解决一些网页特效运行后不能显示效果（例如：jQuery则需要刷新）问题，烈火特别新增网页版演示

　　网页演示：猛击此处

　　运行演示：
