[Yet Another] Single File PHP Script Image Gallery

Description

Here’s a simple Single File PHP Image Gallery Script. It scans a directory for images and displays them in a grid layout. Just place this script in a folder containing images, and it will generate a gallery automatically.

Features

This script dynamically scans the current directory for images and displays them as a gallery. Just place your images in the same folder as the script, and it will generate the gallery automatically. For that reason the first open may be a little bit slower – depending on the number of images you have.

It supports also taking into account mp4 and mov videos and displays them directly (without thumbnailing)

Requirements

The script has been tested on Ubuntu with PHP 8.0

1) GD extension

1. Enable GD in PHP
   • If you’re using XAMPP/WAMP, open php.ini and uncomment the line:

     extension=gd
     

     Then restart Apache.

   • If you’re on Linux, install GD with:

     sudo apt-get install php-gd
     

     Then restart Apache:

     sudo service apache2 restart
     

   • If you’re on Windows, find php.ini, search for ;extension=gd, remove the ;, and restart your server.
2. Check if GD is enabled
   Run this script:

   <?php
   phpinfo();
   ?>
   

   Search for “GD” in the output.

 

Troubleshooting

If you get a 500 error usually means a fatal PHP error.

Enable Error Reporting

Before checking anything else, modify the beginning of your script to show errors:

error_reporting(E_ALL);
ini_set('display_errors', 1);

Check File Permissions

chmod -R 755 thumbnails
