What are some recommended resources or tutorials for learning how to efficiently manage and display a large number of images in PHP?

When dealing with a large number of images in PHP, it is important to efficiently manage and display them to prevent performance issues. One recommended approach is to use pagination to limit the number of images displayed on each page, reducing the load on the server and improving user experience. Additionally, using lazy loading techniques can help to only load images as they are needed, further optimizing performance. 

// Example PHP code snippet for implementing pagination for a large number of images

// Define the number of images to display per page
$imagesPerPage = 10;

// Get the current page number from the URL parameter
$page = isset($_GET['page']) ? $_GET['page'] : 1;

// Calculate the offset for the images query
$offset = ($page - 1) * $imagesPerPage;

// Query database for images with LIMIT and OFFSET
$query = "SELECT * FROM images LIMIT $imagesPerPage OFFSET $offset";
$result = mysqli_query($connection, $query);

// Loop through the results and display the images
while ($row = mysqli_fetch_assoc($result)) {
    echo '<img src="' . $row['image_url'] . '" alt="' . $row['image_alt'] . '">';
}

// Display pagination links
$totalImages = // Get total number of images from database
$totalPages = ceil($totalImages / $imagesPerPage);

for ($i = 1; $i <= $totalPages; $i++) {
    echo '<a href="?page=' . $i . '">' . $i . '</a>';
}
