Android - get image from MYSQL

Question

How can I get an image from MySQL? I'm using an ArrayList, on the MySQL server the image path is stored as varchar.

private void showEmployee(){
    JSONObject jsonObject = null;
    ArrayList<HashMap<String,String>> list = new ArrayList<HashMap<String, String>>();
    try {
        jsonObject = new JSONObject(JSON_STRING);
        JSONArray result = jsonObject.getJSONArray(Config.TAG_JSON_ARRAY);

        for(int i = 0; i<result.length(); i++){
            JSONObject jo = result.getJSONObject(i);
            String id = jo.getString(Config.TAG_ID);
            String name = jo.getString(Config.TAG_NAME);
            String designation = jo.getString(Config.TAG_DESG);
            String salary = jo.getString(Config.TAG_SAL);

            String image = jo.getString(Config.TAG_IMG);

            HashMap<String,String> employees = new HashMap<>();
            employees.put(Config.TAG_ID,id);
            employees.put(Config.TAG_NAME,name);
            employees.put(Config.TAG_DESG,designation);
            employees.put(Config.TAG_SAL,salary);
            employees.put(Config.TAG_IMG,String.valueOf(image));
            list.add(employees);
        }

    } catch (JSONException e) {
        e.printStackTrace();
    }

    ListAdapter adapter = new SimpleAdapter(
            MainActivity1.this, list, R.layout.list_item,
            new String[]{Config.TAG_ID,Config.TAG_NAME,Config.TAG_DESG,Config.TAG_SAL, Config.TAG_IMG},
            new int[]{R.id.id, R.id.name, R.id.desg, R.id.sal, R.id.imageView_1});

    listView.setAdapter(adapter);
}
