6	图片列表样式

上传文件为图片，可展示本地缩略图。

IE8/9 不支持浏览器本地缩略图展示（Ref），可以写 thumbUrl 属性来代替。

import { Upload, Button, Icon } from 'antd';

const props = {
  action: '/upload.do',
  listType: 'picture',
  defaultFileList: [{
    uid: -1,
    name: 'xxx.png',
    status: 'done',
    url: 'https://os.alipayobjects.com/rmsportal/NDbkJhpzmLxtPhB.png',
    thumbUrl: 'https://os.alipayobjects.com/rmsportal/NDbkJhpzmLxtPhB.png',
  }, {
    uid: -2,
    name: 'yyy.png',
    status: 'done',
    url: 'https://os.alipayobjects.com/rmsportal/NDbkJhpzmLxtPhB.png',
    thumbUrl: 'https://os.alipayobjects.com/rmsportal/NDbkJhpzmLxtPhB.png',
  }],
};

ReactDOM.render(
  <div>
    <Upload {...props}>
