What are the potential drawbacks or limitations of using mod_rewrite for image protection in PHP?

One potential drawback of using mod_rewrite for image protection in PHP is that it may not provide sufficient security against determined attackers who can still access the images directly. To enhance security, it is recommended to combine mod_rewrite with additional authentication mechanisms, such as session-based authentication or token-based authentication. 

// Example of combining mod_rewrite with session-based authentication for image protection
session_start();

if (!isset($_SESSION['logged_in']) || $_SESSION['logged_in'] !== true) {
    header('HTTP/1.0 403 Forbidden');
    echo 'Access denied.';
    exit;
}
