イメージアンドロイドからPHPサーバへのアップロード問題

PHPを使用してアンドロイドからサーバーに画像をアップロードしています。画像ファイルがアップロードされていますが、そのファイルを表示しようとすると、壊れた画像を表示するときに、正確に何が問題なのか分かりません。アップロードは、サーバー上に示されAsyncTask AndroidのコードイメージアンドロイドからPHPサーバへのアップロード問題

      } 
      fileInputStream.close(); 
      outputStream.flush(); 
      outputStream.close(); 
PHP Code: 
$file_path = basename($_FILES['uploaded_file']['name']); 
if(move_uploaded_file($_FILES['uploaded_file']['tmp_name'], $file_path)) 
{ 
    echo "success"; 
} else 
{ 
    echo "fail"; 
}

画像で行われます。
