What are some best practices for properly integrating a PHP image gallery script into a website?

Issue: When integrating a PHP image gallery script into a website, it is important to ensure that the script is properly configured and that the gallery displays images correctly. Best practices include organizing images into folders, using a responsive layout for the gallery, and optimizing image loading for faster performance. Code snippet:

<?php
// Define the directory where images are stored
$imageDirectory = 'images/';

// Get all image files from the directory
$images = glob($imageDirectory . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

// Display the images in a responsive gallery layout
echo '<div class="image-gallery">';
foreach ($images as $image) {
    echo '<img src="' . $image . '" alt="Image">';
}
echo '</div>';
?>
