📸 Embedded Gallery SPA

A lightweight, responsive single-page photo gallery built for embedded Linux systems (e.g., OpenWrt).

This project provides a modern web interface for browsing, uploading, and managing photos directly on your embedded device — optimized for low-resource environments with PHP-FPM and Nginx.

🚀 Features

• Single Page Application (SPA) navigation — no full page reloads
• Dynamic gallery with infinite scroll and lazy loading
• GLightbox integration for fullscreen previews and image metadata
• EXIF caching system — stores camera data, lens, aperture, ISO, shutter speed, etc.
• Drag & drop uploads with progress bars and live updates
• Dark / Light themes with persistent preference
• System stats dashboard (CPU, memory, disk, uptime, swap)
• Web shell interface (optional, secure)
• Admin mode with session-based authentication
• Optimized for low RAM and embedded devices

🔧 Installation

1. Copy or extract the ZIP:

   sudo unzip srv_www_final.zip -d /srv/
   
    Set permissions:
   
   

sudo chown -R www-data:www-data /srv/www sudo chmod -R 755 /srv/www

Check PHP-FPM session support:

php -m | grep session

Open your browser:

https://<device-ip>/

🔐 Admin Login

To enable upload and admin features:

Generate a password hash:

php -r "echo password_hash('YourPassword', PASSWORD_BCRYPT);"

Paste the result into includes/config.php:

'upload_password' => '$2y$10$replaceThisWithYourOwnHash',

⚡ Performance Tips

Enable Gzip and Brotli in Nginx for faster page loads:

gzip on; gzip_types text/plain text/css application/javascript application/json; brotli on; brotli_types text/plain text/css application/javascript application/json;

Tune PHP-FPM memory usage for small devices (256MB RAM, 4GB swap):

pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
memory_limit = 64M

📦 Updating

Use the included helper script:

sh update-www.sh srv_www_final.zip

It will back up the old site, extract the new one, and fix permissions automatically. 🧑‍💻 Author
