Built for Joomla! 6, the extension uses Joomla’s native Dialog system without adding a separate third-party lightbox library. It is suitable for screenshots, tutorials, documentation, product illustrations, and image-rich articles.

Key Features

• Automatic image lightboxes: Convert image links in article content into clickable lightbox triggers.
• Optional automatic linking: Make standalone images clickable without manually adding a link to each image.
• Selective activation: Apply the lightbox to all eligible image links or only images and links carrying your chosen CSS class.
• Responsive image display: Keep enlarged images within the available screen space.
• Flexible dialog sizing: Use automatic sizing or set your preferred width and height.
• Optional image captions: Use the link title, image title, or image alt text as the dialog heading, or disable headings.
• Hover and focus indicator: Display an optional expand icon when visitors hover over an image or focus its link with the keyboard.
• External image control: Choose whether images hosted on other domains should be processed.
• Subdirectory support: Handle image paths on Joomla installations located in a subdirectory.
• English and Turkish interface: Configure the extension using the included language files.

Built Around Joomla

JT Image Lightbox Pro uses Joomla’s content plugin architecture, native Dialog API, and Web Asset Manager. Its styles are scoped to the extension’s lightbox elements to reduce interference with other dialogs.

The administrator settings provide controls for image selection, captions, dialog dimensions, and the expand icon. No custom JavaScript or template editing is required for standard setup.

License and Updates

Manage license activation, verification, and deactivation from the plugin settings. Successful license actions save their status automatically.

Package updates are delivered through Joomla’s extension update system. Access to updates and support depends on your purchased license.

Getting Started

1. Install the package using the Joomla administrator.
2. Enable the Content – JT Image Lightbox plugin.
3. Choose automatic processing or CSS class-based activation.
4. Enable automatic linking if you want standalone images to open in the lightbox.
5. Configure captions, sizing, and the optional expand icon.

For selective activation, the default trigger class is jt-lightbox.

Supported Content and Image Formats

The plugin processes images embedded in article text. Supported image URL extensions include JPG, JPEG, PNG, GIF, WebP, AVIF, SVG, and BMP. Display support depends on the visitor’s browser.

Joomla’s separate Intro Image and Full Article Image fields are not processed. Automatic linking also excludes standalone images inside picture elements.
