Auto Lightbox for Blocks

Automatically adds a responsive lightbox to your WordPress block images. Supports galleries and lazy-loading.

Description

Auto Lightbox for Blocks is a lightweight, zero-configuration plugin that automatically adds a beautiful lightbox to your WordPress image and gallery blocks. Built with the powerful GLightbox library.

Key Features:

• Zero Configuration: Works out of the box with standard WordPress blocks (.wp-block-image, .wp-block-gallery).
• Original Image Detection: Automatically finds and displays the full-size image, even if you inserted a smaller size.
• Lazy Load Support: Fully compatible with WordPress native lazy loading.
• Accessibility: Built with accessibility in mind (ARIA support, keyboard navigation).
• Smart Grouping: Automatically groups images in the same gallery block. Option to group ALL page images.
• Touch Friendly: Swipe navigation for mobile devices.
