如何使用不同的参数将图像发送到服务器

Question

我正在开发一个应用程序，用户必须在使用该应用程序之前注册他/她自己。我在注册时发送的参数很少。还有一个imageview ..我正在做这个代码

    imgvw1.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                selectImage();

            }
        });


        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();

        StrictMode.setThreadPolicy(policy); 

        btn_submit.setOnClickListener(new  OnClickListener() {

            @Override
            public void onClick(View v) {
          if(name.getText().toString().trim().length()>0 )
          {

              if(pass.getText().toString().trim().length()>0)
              {
                  if(email.getText().toString().trim().length()>0)
                  {

                      if(age.getText().toString().trim().length()>0)
                      {

                          String regName = name.getText().toString().trim();
                            String regPass = pass.getText().toString().trim();
                            String regEmail = email.getText().toString().trim();
                            String regAge = age.getText().toString().trim();


              String url ="http://tokerapp.com/ws/register.php?username="+ regName + "&password=" + regPass + "&email=" + regEmail + "&age=" + regAge + "&sex=qee&Device_Id=12332weewr";
             try {
                 ArrayList<NameValuePair> postParameters = new ArrayList<NameValuePair>();

                // ArrayList<NameValuePair> nameValuePairs = null;

                postParameters.add(new BasicNameValuePair("file", "<thumbnail>"));


            String res= CustomHttpClient.executeHttpPost(url, postParameters); 

            Log.e("response",""+res);
            } catch (Exception e) {
                e.printStackTrace();
            } 
          }
          }
              }
          }
          else
          {
              Toast.makeText(getApplicationContext(), "Invalid Entry", 1000).show();
          }
          }
            }
        );

    }

    protected void selectImage() {
        // TODO Auto-generated method stub

        final CharSequence[] options = {  "Choose from Gallery","Cancel" };

        AlertDialog.Builder builder = new AlertDialog.Builder(Registration.this);
        builder.setTitle("Add Photo!");
        builder.setItems(options, new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int item) {
                /*if (options[item].equals("Take Photo"))
                {
                    Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                    File f = new File(android.os.Environment.getExternalStorageDirectory(), "temp.jpg");
                    intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
                    startActivityForResult(intent, 1);
                }*/
                 if (options[item].equals("Choose from Gallery"))
                {
                    Intent intent = new   Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                    startActivityForResult(intent, 1);

                }
                else if (options[item].equals("Cancel")) {
                    dialog.dismiss();
                }
            }
        });
        builder.show();
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data)
    {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK) 
        {
            if (requestCode == 1)
            {
                Uri selectedImage = data.getData();
                String[] filePath = { MediaStore.Images.Media.DATA };
                Cursor c = getContentResolver().query(selectedImage,filePath, null, null, null);
                c.moveToFirst();
                int columnIndex = c.getColumnIndex(filePath[0]);
                String picturePath = c.getString(columnIndex);
                c.close();
                Bitmap thumbnail = (BitmapFactory.decodeFile(picturePath));
                Log.w("path of image from gallery......******************.........", picturePath+"");
                imgvw1.setImageBitmap(thumbnail);
            }
        }
    }

//}
}

并从webservice获得此响应。

{“message”：“图片未上传”，“状态”：“STATUS_FALSE”}

请帮我解决这个问题，谢谢你提前
