-- Create the database
CREATE DATABASE IF NOT EXISTS `imagelightbox`;
-- Use the created database
USE `imagelightbox`;
-- Create the `images` table
CREATE TABLE IF NOT EXISTS `images` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`images` varchar(255) NOT NULL,
`title` varchar(255) NOT NULL,
`date` date NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;
-- Insert initial data into the `images` table
INSERT INTO `images` (`id`, `images`, `title`, `date`) VALUES
(1, 'Spacify Catalogue Commercial Online_page-0038.jpg', 'Spacify Catalogue Commercial Online_page-0038', '2024-12-23'),
(2, 'Spacify Catalogue Commercial Online_page-0025.jpg', 'Spacify Catalogue Commercial Online_page-0025', '2024-12-23'),

(8, 'Spacify Catalogue Commercial Online_page-0001.jpg', 'Spacify Catalogue Commercial Online_page-0001', '2024-12-23');
-- Ensure the `id` column auto-increments correctly
ALTER TABLE `images`
MODIFY `id` int(11) NOT NULL AUTO_INCREMENT, AUTO_INCREMENT=9;
-- Commit the transaction
COMMIT;

if (!$conn) {
die("Connection Failed: " . mysqli_connect_error());
}
$sql = "SELECT images, title FROM images";
$result = mysqli_query($conn, $sql);
while ($row = mysqli_fetch_assoc($result)) {

<div class="col-lg-3 col-md-4 col-sm-6 mb-4">
<div class="gallery">
<a href="images/<?php echo $row['images']; ?>" class="big">
<img decoding="async" src="images/<?php echo $row['images']; ?>" alt="<?php echo htmlspecialchars($row['title']); ?>" class="gImg img-fluid" style="width: 100%; cursor: pointer;">
