You can try sample below :

  JSONObject new_jo = jo.getJSONObject("image");
  String pic = new_jo.getString("photo");
  String thumbnail = new_jo.getString("thumb");

You are wrong. image tag is not JsonArray. It is JsonObject. So use this one.

for (int i = 0; i < ja.length(); i++) {

  JSONObject jo = (JSONObject) ja.get(i);

  String headline =jo.getString("HeadLine");

  JSONObject jsonimage=jo.optJSONObject("image");


  String str_photo=jsonimage.optString("photo");

 }

image is JSONObject instead of JSONArray so you can get photo and thumb values as:

for (int i = 0; i < ja.length(); i++) {

JSONObject jo = (JSONObject) ja.get(i);

  String h=jo.getString("HeadLine");
  // get image JSONObject from jo
  JSONObject jsonimage=jo.optJSONObject("image");

  // get photo anf thumb values from jsonimage jsobobject
   String str_photo=jsonimage.optString(photo);
   ...
}

Follow these steps in order to parse the json
1) Create JSONObject for getting the result string.
2) Create JSONArray for getting array from "newsitem" tag
3) Create JSONObject for 
   3.1) headline tag
   3.2) caption tag
   3.3) image tag
4) Create again JSONObject for
   4.1) photo tag
   4.2) thumb tag


Now how to achieve this

 JSONObject jsonObj=new JSONObject(jsonstring);
 JSONArray newsItemObj=jsonObj.getJSONArray("newitem");

for(int i=0;i<newsItemObj.length();i++)
{
   String headline=newsItemObj.getString("headline");
   String caption=newsItemObj.getString("caption");

   JSONObject imageObject=newsItemObj.getJSONObject("image");

    String photo=imageObject.getString("photo");
    String thumb=imageObject.getString("thumb");
