What potential pitfalls should be considered when using PHP scripts to redirect image requests and how can they be avoided?

Potential pitfalls when using PHP scripts to redirect image requests include increased server load, slower loading times for images, and potential security vulnerabilities if not properly sanitized. To avoid these issues, it is recommended to use server-side redirects instead of PHP scripts whenever possible and to ensure that the image requests are handled efficiently. 

<?php
// Check if the request is for an image file
if (preg_match('/\.(jpg|jpeg|png|gif)$/i', $_SERVER['REQUEST_URI'])) {
    // Use server-side redirect instead of PHP script
    header('Location: ' . $_SERVER['REQUEST_URI'], true, 301);
    exit;
}
