Lightbox for Gallery & Image Block

by Johannes Kinast

Version: 1.16

Download
Description

This WordPress Plugin adds a simple & lightweight Lightbox to the standard WordPress Gallery & Image Block. It detects if a post contains a Gallery or Image Block and then loads & initialize baguetteBox.js, a pure JavaScript Lightbox script without any dependencies and a modern minimal look.

There is no lock in effect. It does not add a new Block Editor/Gutenberg Block and relies solo on the standard WordPress Gallery and Image Block. You can deactivate this plugin at any time and your Gallery and Image Blocks will work as they’ve done before. Just without the lightbox.

Just one important thing to remember: You always have to select Link Link to image file or Link images to media file (see screenshots below) for all of your Image & Gallery Blocks to work properly. If you choose None or Link to attachment page it will not work. But that’s fine if you don’t want the Lightbox for a specific Image or Gallery.

Features

Here are the features of baguetteBox.js:

  • Written in pure JavaScript
  • No dependencies (e.g. jQuery)
  • Image captions support
  • Responsive
  • Supports swipe gestures
  • Around 13 KB, 7 KB gzipped

Works with

  • Gallery Block (Default Block)
  • Image Block (Default Block)
  • Media and Text Block (Default Block)
  • Gallery (Default Classic Editor Gallery)
  • CoBlocks Gallery Collage / Masonry / Offset / Stacked
  • Meow Gallery (+ Gallery Block)
  • GenerateBlocks Image (Set Enable Dynamic Data Link source to Single image)

Don’t forget to select Link to Media File for all of your Galleries & Images to work properly.

Notice: At the moment, just Blocks inside a post are supported. Not Blocks in a Widget. You can make it work but have to enqueue the necessary style & script yourself. See FAQ –> How to enqueue the necessary assets (script & style) for blocks outside of posts or for block types that are not supported by default?

  1. Upload the folder gallery-block-lightbox to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. Add a Gallery or Image Block to your Post and set Link to Media File
  4. Check your Gallery or Image with Lightbox on the front end by clicking on an image

  2. Set <em>Link</em> to <em>Link to image file</em> on your Image Block<br />

    Set Link to Link to image file on your Image Block

  3. Set <em>Link</em> to <em>Link images to media file</em> on your Gallery Block<br />

    Set Link to Link images to media file on your Gallery Block

When I click on an image, nothing happens

Check if you used the built in Gallery Block and if Link to is set to Media File in the Block sidebar. On an Image Block choose Add Link at the Toolbar.

Does it work for single images?

Yes! Just set the Link at the Toolbar to Media File

Can I deactivate the Lightbox for a single Image or Gallery?

Set Media File to None or remove the Link.

Is there a way to set the default Link to option to Media File?

Since WordPress 5.6 you can now set the default behavior for Link to. Go to yourblog.com/wp-admin/options.php and search for image_default_link_type. Set the value to file and hit save. This will apply to all new Image & Gallery Blocks.

Or you can add the follow snipped (WordPress 5.7+ / PHP 7.4+) to your functions.php:
add_filter( 'option_image_default_link_type', fn () => 'file' );

How can I add my own Block? / Can I change the CSS selector?

You can change the CSS selector to a gallery (or galleries) containing <a> tags used by baguetteBox.js with the baguettebox_selector filter:
add_filter( 'baguettebox_selector', function( $selector ) { return $selector . ',.my-gallery'; } )
You can override the full selector by just returing your selector e.g. to show all images in your post in one lightbox (not per Gallery/Image Block):
add_filter( 'baguettebox_selector', function() { return '.entry-content'; } )

How to enqueue the necessary assets (script & style) for blocks outside of posts or for block types that are not supported by default?

If you use a Gallery or Image Block outside a post e.g. inside a Widget and want to apply the Lightbox, you need to ensure that the required baguettebox assets (script & style) are queued using the baguettebox_enqueue_assets filter.

If the Widget is on every page or the majority of pages, you can just enqueue the baguettebox assets everywhere. Just add the following snippet to functions.php:
add_filter( 'baguettebox_enqueue_assets', '__return_true' );
If your Widget is just at the front page, use is_front_page():
add_filter( 'baguettebox_enqueue_assets', function( $enqueue_assets ) { return is_front_page(); } );
If you want to use the Gallery & Image Block Lightbox plugin with a block type that is not supported by default, you can make use of the has_block() function. For instance, in the case of the Kadence Blocks Advanced Gallery, use:
add_filter( 'baguettebox_enqueue_assets', function ( $enqueue_assets ) {
return $enqueue_assets || has_block( 'kadence/advancedgallery' );
} );
Of course, in the previous example you also have to add the appropriate baguettebox selector, i.e.
add_filter( 'baguettebox_selector', function( $selector ) {
return $selector . ',.wp-block-kadence-advancedgallery';
} );

Can I change or disable the animation on image transitions?

By default, baguetteBox.js shows a slide-in animation on image transitions. You can change it to the following filter to 'fadeIn':
add_filter( 'baguettebox_animation', function () { return 'fadeIn'; } );
Or disable the animation completely with 'false':
add_filter( 'baguettebox_animation', function () { return 'false'; } );

A worthy successor to WP Featherlight

By skirridsystems on March 21, 2025

My favourite lightweight lightbox viewer closed recently and I needed something to replace it.

This plugin is super lightweight, and has exactly the same admin interface, i.e. nothing to do, just install it and watch the magic happen on existing images and galleries. What's not to like.

Very helpfull Lightbox, lightweight, zero configuration

Lean, beautiful, accessible, unobtrusive lightbox for users of the block editor

By Bjarne Oldrup (oldrup) on August 9, 2024

Lightbox for Gallery & Image Block is a lean, efficient lightbox solution for the core WordPress Gallery and Image blocks. What I especially like, over the core WordPress light box feature:

  • Prettier; subjective, I know, but I think it is.
  • Works for entire galleries; core WP is/was individual image only.
  • Super lean; 9kb of JavaScript, no dependencies.
  • Easy to style with classes and ID's.
  • Pretty good accessibility; works with keyboard navigation and focus outline.
  • No plugin lock-in; enabled by linking the image to media file, a core functionality.

The best plugins for WordPress are, in my opinion, the ones that you can enable when they improve the experience, and disable if it, for some reason, doesn't work well with the website anymore. That leaves no traces behind, and requires no cleaning up the content afterward. Lightbox for Gallery & Image Block is such a plugin. I enjoy using it a lot.

It does not support, not include code for, lightboxing PDF'files and videos. That might be an advantage or disadvantage, depending on your needs. In my opinion, viewing PDF files is best taken care of by the browser chosen by the visitor, and embedded videos have other great plugins available for addressing overlays and privacy.

In conclusion, a robust solution for a very specific task, nothing more, nothing less.

Five starts ⭐⭐⭐⭐⭐
