简单介绍一下这个插件的使用小案例，首先先看一下CI框架中的目录结构
这是我们一般使用CI框架时候的目录结构，其中assets是jQuery-File-Upload带的要用到的静态文件，比方说CSS,JS,Image图片等，可以大体看一下
目录放对了之后，我们就可以写我们想要的MVC结构里面的内容了，首先我们看一下View里面的内容

/* End of file upload.php */
/* Location: ./application/controllers/upload.php */Controller这里可以控制上传的路径，把参数传给一个图片类UploadHandle.php，这里放在了libraries里面了，这里是实际的操作图片的地方。存储路径只需要在C里面初始化类的时候改变参数既可。
