在FaceBook Graph API v2.4中，如何在JSON提要中包含帖子的图片/图标？

Question

我能够在FaceBook中获取公共群组页面的JSON帖子Feed。但是，Feed仅限于以下内容：

{
   "data": [
      {
         "message": "RT Ad Age: Creatives rejoice! The need for speed in digital is putting copy testing under fire http://buff.ly/1NCNUYm",
         "created_time": "2015-09-16T19:17:22+0000",
         "id": "100893736659527_876911945724365"
      },
      {
         "message": "Smart Design Means Treating Your Users Like Friends.",
         "created_time": "2015-09-15T19:17:07+0000",
         "id": "100893736659527_876382499110643"
      },
      {
         "message": "Amazon Puts Another Nail in Flash\u2019s Coffin http://buff.ly/1NzwFal (via Digiday)",
         "created_time": "2015-09-14T17:25:52+0000",
         "id": "100893736659527_875881985827361"
      },
      {
         "message": "Is Belvedere Vodka Good Enough For James Bond?",
         "created_time": "2015-09-11T19:17:14+0000",
         "id": "100893736659527_874377899311103"
      },
      {
         "message": "RT MailChimp: Our GIPHY integration makes it easy to upload GIFs into your campaign. Exciting, right? http://buff.ly/1JQChqz",
         "created_time": "2015-09-10T19:17:14+0000",
         "id": "100893736659527_873864092695817"
      }
}

我能够获取消息文本，created_time和id。如何添加帖子的图片/图标？
