    String queryString = "";
    Iterator<NameValuePair> itr = params.iterator();    

    while(itr.hasNext()) {
        NameValuePair nvp = itr.next();         

        //TODO if ....
        try {
            if(Arrays.asList(params).contains("image")) {
                Log.w(TAG, "if(Arrays.asList(params).contains('image'))");
