FineUploader既是开源的又是收费的，这个没搞懂。
先看效果：
.....
很清爽。
成功和失败很清楚。
从网上找到了这个插件的几个文件：
- fineuploader-4.1.0.min.css
- jquery.fineuploader-4.1.0.min.js
- loading.gif
- processing.gif
后2个是动画效果。
环境：
ASP.NET MVC 4
使用到的文件：
- fineuploader-4.1.0.min.css
- jquery.fineuploader-4.1.0.min.js
- loading.gif
- processing.gif
- jquery-1.8.3.min.js
