js swipe 图片滑动控件实现 任意尺寸适用任意屏幕

http://www.swiper.com.cn/
http://www.idangero.us/swiper/demos/

解决问题点:

1.先得到图片真实的宽高, 根据真实宽高 等比例

2.调用的控件 宽高的计算 其实是 获取  .swiper-container 样式的宽和高,所以此样式的宽高要设定好。

宽100%   高 则根据 真实图片的 比例来 

 72     $(".swiper-container").css("height",$(".swiper-container").width()/imageRealWidth*imageRealHeight);                                                                         
3.再采用cookie 技术 否则每次加载 页面都new Image 从性能角度考虑 更优
