What approach did the user try to implement to navigate through the pages of the gallery and what challenges did they encounter?

The user tried to implement a pagination system to navigate through the pages of the gallery, but they encountered challenges in correctly displaying the images on each page. To solve this issue, the user can use the following PHP code snippet to implement pagination in their gallery: 

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

// Get the total number of images in the gallery
$totalImages = count($images);

// Calculate the total number of pages
$totalPages = ceil($totalImages / $imagesPerPage);

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

// Calculate the starting index for the images on the current page
$startIndex = ($page - 1) * $imagesPerPage;

// Display the images on the current page
for ($i = $startIndex; $i < min($startIndex + $imagesPerPage, $totalImages); $i++) {
    echo '<img src="' . $images[$i] . '" alt="Image ' . ($i + 1) . '">';
}

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