Downloading file is corrupted - header

I have be trying to figure out what is wrong but every time i download the image and try to open it, it says that the file is corrupt.

$h is the path which is pulled from the database, the $h displays the image on the page successfully but I dont get why it wont download. Any ideas ??

header("Pragma: public"); // required   
header("Cache-Control: private",false); // required for certain browsers  
header('Content-Length: '. filesize("../".$h));  
header('Content-Type: application/octet-stream');  
header('Content-Disposition: inline; filename="'.md5($h).$ext.'"');  
header('Content-Transfer-Encoding:binary');  
header('Cache-Control: must-revalidate, post-check=0, pre-check=0');  

readfile("../".$h);

Maybe try to add the following 2 commands before your readfile line.

ob_clean();
flush();
readfile($file);

These lines were in the example for the PHP docs on readfile.

Try this:

$localPath = realpath("../$h");
if (!file_exists($localPath)) {
  exit("Cannot find file located at '$localPath'");
}

header('Pragma: public'); // required   
header('Content-Length: '.filesize($localPath));  
header('Content-Type: application/octet-stream');  
header('Content-Disposition: attachment; filename="'.md5($localPath).'.'.$ext.'"');  
header('Content-Transfer-Encoding: binary');  
header('Cache-Control: must-revalidate, post-check=0, pre-check=0', false);  
header('Cache-Control: private', false); // required for certain browsers  

readfile($localPath);
exit;
