Very Simple PHP Gallery

This is a very simple PHP based image Gallery. It takes all images from or (or potentially multiple) directories and presents them as a simple web gallery. It will autogenerate thumbnails for the gallery overview and also do variable pagination. There are some simple keyboard shortcuts as well.

Running it

A webserver with PHP support and the php-gd extension (for thumbnails) is required. An example config for nginx with php-fpm might look like this:

worker_processes 4;

events {
    worker_connections  256;
}


http {
  include       mime.types;
  default_type  application/octet-stream;

  access_log    /var/log/nginx/access.log;
  error_log     /var/log/nginx/error.log info;

  sendfile        on;
  keepalive_timeout  65;

  upstream php-default-handler {
    server unix:/run/php-fpm7/php-fpm.sock;
  }

  server {
    listen 80;
    listen [::]:80;
    server_name gallery.example.com;

    fastcgi_buffers 64 4K;

    gzip on;
    gzip_vary on;
