Are there any potential pitfalls to be aware of when using PHP to handle image display on a website?

One potential pitfall when using PHP to handle image display on a website is the risk of exposing sensitive file paths or directory structures to users. To mitigate this security risk, it is important to ensure that the image paths are properly sanitized and validated before displaying them on the website. 

<?php
// Example of sanitizing and validating image path before displaying
$image_path = 'images/image.jpg';

// Validate image path
if (strpos($image_path, 'images/') !== false) {
    // Display image
    echo '<img src="' . htmlspecialchars($image_path) . '" alt="Image">';
} else {
    // Handle invalid image path
    echo 'Invalid image path';
}
?>
