Как загрузить разные изображения в два ImageView в Firebase?

Question

В этом сценарии у меня есть два ImageViews, и моя проблема в том, что я могу загрузить сигнатурное изображение на мой Firebase, но не на изображение посетителей. Когда я попытался загрузить два ImageView на одну кнопку. .

вот мой код для MainActivity. xml

public class MainActivity extends AppCompatActivity {

EditText fullname, companyname, mobilenumber, emailaddress, salespersonnel, imagecaption;
TextView dateandtime;
Button buttonsave, buttonclear, buttoncapture, buttonsign, buttongetimage;
DatabaseReference reference;
Uri FilePathUri, FilePathUri2;
StorageReference storageReference, storageReference2b;
int Image_Request_Code = 7;
ProgressDialog progressDialog;
ImageView visitorimage, signatureimage;
Visitors visitors;
String pathtofile;

Calendar calander;
SimpleDateFormat simpledateformat;
String Date;
TextView DisplayDateTime;
private int requestcode;
private int resultcode;
private Intent data;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    storageReference = FirebaseStorage.getInstance().getReference("Visitors Signature");
    storageReference2b = FirebaseStorage.getInstance().getReference("Visitors Image");
    progressDialog = new ProgressDialog(MainActivity.this);

    fullname = (EditText) findViewById(R.id.full_name);
    companyname = (EditText) findViewById(R.id.company_name);
    mobilenumber = (EditText) findViewById(R.id.mobile_number);
    emailaddress = (EditText) findViewById(R.id.email_address);
    salespersonnel = (EditText) findViewById(R.id.sales_personnel);
    imagecaption = (EditText) findViewById(R.id.image_caption);

    dateandtime = (TextView) findViewById(R.id.time_date);

    buttonsave = (Button) findViewById(R.id.btn_save);
    buttoncapture = (Button) findViewById(R.id.btn_capture);

    if (Build.VERSION.SDK_INT >= 23){
        requestPermissions(new String[]{Manifest.permission.CAMERA, 
Manifest.permission.WRITE_EXTERNAL_STORAGE},2);
    }


    buttonsign = (Button) findViewById(R.id.btn_getsign);
    buttongetimage = (Button) findViewById(R.id.btn_getimage);
    buttonclear = (Button) findViewById(R.id.btn_clear);

    visitorimage = (ImageView) findViewById(R.id.visitor_image);
    signatureimage = (ImageView) findViewById(R.id.image_view);

    reference = FirebaseDatabase.getInstance().getReference().child("Visitors");

    visitors = new Visitors();


    String date_n = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss", Locale.getDefault()).format(new 
Date());
    TextView date = (TextView) findViewById(R.id.time_date);
    date.setText(date_n);

    calander = Calendar.getInstance();
    simpledateformat = new SimpleDateFormat("HH:mm:ss");
    Date = simpledateformat.format(calander.getTime());


    buttonsave.setOnClickListener(new View.OnClickListener() {
