آپلود عکس در دیتابیس لوکال؟ (حل نشده)

سلام کد قسمت سرور (php) اینه:

 <?php
header('content-type: bitmap; charset=utf-8');
if(isset($_REQUEST["encoded_string"]))
{
  $encoded_string = $_REQUEST["encoded_string"];
  $image_name = $_REQUEST["image_name"];
  $decoded_string = base64_decode($encoded_string);
  $path = 'images/'.$image_name;
  $file = fopen($path, 'wb');
  $is_written = fwrite($file, $decoded_string);
  fclose($file);

  if($is_written > 0)
  {
    $connection = mysqli_connect('localhost','root','','dbname');
    $query = "INSERT INTO db_photo (photo_name,photo_path) VALUES ('$image_name','$path');";

    $result = mysqli_query($connection,$query);

    if($result)
    {
      echo "success";
    }
    else
    {
      echo "failed";
    }

    mysqli_close($connection);
  }
}
?>

به وسیله این کد می تونی تصویری که به صورت base64 از سمت اندروید ارسال میشه را در هاست ذخیره میکنه و ادرس فایل را در دیتابس می نویسه

کد sql جدول تصاویر:

 CREATE TABLE IF NOT EXISTS `db_photo` (
  `photo_id` int(10) unsigned NOT NULL AUTO_INCREMENT,
  `photo_name` varchar(30) COLLATE utf8_persian_ci NOT NULL,
  `photo_path` varchar(50) COLLATE utf8_persian_ci NOT NULL,
  PRIMARY KEY (`photo_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8 COLLATE=utf8_persian_ci AUTO_INCREMENT=35 ;

سمت اندروید:

 public void uploadImage(View v) {
		// When Image is selected from Gallery
		if (imgPath != null && !imgPath.isEmpty()) {
			prgDialog.setMessage("Converting Image to Binary Data");
			prgDialog.show();
			// Convert image to String using Base64
			encodeImagetoString();
		// When Image is not selected from Gallery
		} else {
			Toast.makeText(
					getApplicationContext(),
					"You must select image from gallery before you try to upload",
					Toast.LENGTH_LONG).show();
		}
	}
