线上Demo地址：http://www.plupload.com/example_queuewidget.php
可以批量上传图片和zip文件。我看我是越来越懒了，啥都不想介绍了，自己看吧孩子们。
The developers of TinyMCE brings you Plupload, a highly usable upload handler for your Content Management Systems or similar.
Plupload is currently separated into a Core API and a jQuery upload queue widget this enables you to either use it out of the box or write your own custom implementation.
Features：
1. Drag/drop support of files is currently only available in Firefox 3.5+. WebKit/Opera doesn't support this feature yet.
2. Image resizing is only possible on Firefox 3.5+ and only at a fixed quality. WebKit/Opera doesn't support direct data access to the selected files.
3. File type filtering is currently not supported by any browser. But we fill the HTML 5 accept attribute so once the support is there it will work.
