Files Gallery Improvements
Additional features and compatibility improvements for Files Gallery 0.15.3.
Files Gallery is a PHP-based file and image gallery developed by Imagevue Co., Ltd. These independently developed improvements extend the original application with modern PHP compatibility improvements, thumbnail management, revised caching behavior, and additional file filtering.
The improvements are designed for an existing, properly licensed Files Gallery 0.15.3 installation. They are not an official Files Gallery release and do not include the original application or license keys.
Try our live demo with all four improvements installed. Be sure to click the Generate Thumbnails button in the upper-right corner to see how the Thumbnail Manager works.
What’s improved over Files Gallery 0.15.3?
- PHP 8.5 compatibility (v1.0.0): Addresses deprecated image-resource cleanup calls encountered with PHP 8.5. This targeted patch does not guarantee compatibility with every PHP environment.
- Thumbnail Manager (v1.0.0): Adds a password-protected interface for generating normal and retina thumbnails throughout your galleries. Includes persistent processing queues, pause and resume, and cleanup of cached thumbnails for deleted images.
- Improved cache handling (v1.0.0): Adjusts PHP response caching to use private cache headers and a shorter cache lifetime, helping browsers display updated gallery content more consistently.
- Hidden-file filtering (v1.0.2): Keeps dotfiles, hidden directories, Thumbnail Manager support files, and certain server error pages out of gallery listings. This does not replace server-side access controls.
