    <script src="__PUBLIC__/plugins/qiniu/plupload/plupload.full.min.js"></script>
    <script src="__PUBLIC__/plugins/qiniu/qiniu.js"></script>
    <script src="__PUBLIC__/plugins/qiniu/newUi.js"></script>
    html页面:
    <tr>
    <th valign="top">图片信息:</th>
    <td><a href="javascript:;" class="filePicker" id="filePicker2">上传图片</a><b>最多可上传6张图片,每张图片大小不超过5M,支持gif,jpg,png,jpeg格式文件</b>
    <div id='picBox2'></div>
