You can use readfile of PHP to read a file and return to browser. An example can be use like this:

<?php

$file = "/data/admin_assets/upload_files/Photos/nala/start_photo.jpg";

if (file_exists($file)) {
    header('Content-Description: File Transfer');
    header('Content-Type: application/octet-stream');
    header('Content-Disposition: attachment; filename="'.basename($file).'"');
    header('Expires: 0');
    header('Cache-Control: must-revalidate');
    header('Pragma: public');
    header('Content-Length: ' . filesize($file));
    readfile($file);
    exit;
}
?>

And make sure you set permission so that web server can access that directory: data/admin_assets/upload_files/Photos/nala/
