Problem with save as box at Safari for Windows

Hello, i have a PHP script that will pop up a save as dialog box.
This script works well at Firefox and IE7, but when i test it with Safari for Windows.
It will download the PHP script itself and not the file that i want to give to user.
Can someone help me, pls? I really need this. Thanks in advance....

<?php
      include("database_setup.php");

      $getType = $_POST['photo_type'];
      $getName = $_POST['photo_name'];
      $getEmail = $_POST['textfield'];
      $user = $_SESSION["username"];

      if(strcmp($getType, "home") == 0) {
            $file = "Homepage_Photo";
            if(copy("./homepage_photo/" . $getName, "./encrypted_files/".$getName)) {
                  $location = "./encrypted_files/" . $getName;
            }
      }
      else if(strcmp($getType, "watermark") == 0) {
            $file = "Watermarked_Photo";
            if(copy("./watermarked_photo/" . $getName, "./encrypted_files/".$getName)) {
                  $location = "./encrypted_files/" . $getName;
            }
      }

      if(strcmp($getEmail, $user) != 0) {
            $_SESSION["downloadMsg"] = "Sorry, username that you input : $getEmail, is not a valid user";
            header("Location: ./photo.php");
      }
      else {
            $gabung = "encrypt " . $location . " " . $getEmail;
            $aes = `java AESfile $gabung`;

            if(strcmp(trim($aes), "Encryption Success") == 0) {
                  @unlink($location) or die("Cannot delete file");
                  $onlyName = substr($getName, 0, strlen($getName) - 4);
                  $fileName = $onlyName . ".uow";
                  $fileLoc = "./encrypted_files/" . $fileName;

                  header("Content-disposition: attachment; filename=".$fileName);
                  header("Content-type: application/octet-stream");
                  header("Pragma: no-cache");
                  header("Expires: 0");

                  $fp = fopen("$fileLoc","r");
                  $str = fread($fp, filesize($fileLoc));
                  echo $str;
                  fclose($fp);
            }
      }
?>

Well, i got an answer from other forums
I changed my code to readfile($fileLoc), and now Safari can download the file.
But when i want to download a jpg image, Safari will automatically open the file @ browser. I want user to download the image.
Can someone help me, pls? Thx
