What are some best practices for organizing and displaying images in PHP, especially when dealing with large quantities?

When dealing with large quantities of images in PHP, it is important to organize and display them efficiently to ensure optimal performance. One best practice is to store images in a structured directory hierarchy based on categories or dates. Additionally, using pagination to limit the number of images displayed on a single page can help improve loading times. 

// Example of organizing and displaying images in PHP

// Define the base directory for storing images
$baseDir = 'images/';

// Get list of image files from the directory
$imageFiles = glob($baseDir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

// Display images using pagination
$perPage = 10;
$page = isset($_GET['page']) ? $_GET['page'] : 1;
$start = ($page - 1) * $perPage;
$imagesToDisplay = array_slice($imageFiles, $start, $perPage);

// Display images
foreach ($imagesToDisplay as $image) {
    echo '<img src="' . $image . '" alt="Image">';
}

// Pagination links
$totalPages = ceil(count($imageFiles) / $perPage);
for ($i = 1; $i <= $totalPages; $i++) {
    echo '<a href="?page=' . $i . '">' . $i . '</a>';
}
