Download the PHP package fivejars/booster_bigger_picture without Composer

Booster Bigger Picture

The module provides integration with the Bigger Picture library as a solution for Lightbox functionality.

It also provides the Responsive thumbnail field formatter for media reference fields, which renders a referenced media item's thumbnail as a responsive image. That formatter was absorbed from the Media Responsive Thumbnail module, which is no longer a dependency. The plugin ID is unchanged (media_responsive_thumbnail), so existing displays keep working.

Formatters:

• Responsive thumbnail (media reference fields)
• @todo Image formatter
• @todo Responsive image formatter

Requirements

• Drupal core ^11.4
• media and responsive_image (core modules)

Drupal 11.4 is the minimum because the formatter passes image attributes through the #attributes property and the file URL generator through the parent constructor, neither of which exists in earlier core.

Recommended modules

• Media Thumbnails Video - Recommended for correct work with local video media type.

Installation

• Install as you would normally install a contributed Drupal distribution. For further information, see Installing Drupal.
• Install Bigger picture library to 'libraries' directory (using composer.libraries.json or manual)

Configuration

Go to the target entity type display settings and setup formatter configuration.

Attributes

The responsive_image_formatter theme hook carries two separate attribute bags:

• attributes — belongs to the <img> element. Core owns it and merges it into the image since Drupal 11.4 (see change record 3554585). Use it for classes, loading, data-* meant for the image itself.
• link_attributes — added by this module, belongs to the <a> wrapping the image. All lightbox data-* attributes (data-lightbox-group, data-type, data-img, data-sources, …) live here. The module casts it to an Attribute object in preprocess, because core only does that automatically for attributes, title_attributes and content_attributes.

Migration path

Upgrading from a release that still depended on Media Responsive Thumbnail:

1. Update the code and run the database updates:

   bigger_picture_update_11001() re-saves every entity view display that used the formatter, so its dependency moves from media_responsive_thumbnail to bigger_picture, and then uninstalls the old module. If any display still depends on the old module after the re-save, the update aborts instead of letting the config manager delete it.

2. The formatter ID is unchanged, so no display needs reconfiguring and no content changes.

3. drupal/media_responsive_thumbnail is no longer required and drops out on the next composer update. Remove any site-level patch targeting it — in particular the workaround for issue #3350081, which is obsolete: the formatter now always renders the media thumbnail.

4. Breaking change for themers. Two render array properties changed:

   Before	After
   #item_attributes (image attributes)	#attributes
   #attributes (lightbox link attributes)	#link_attributes

   Update any template that merges attributes into an image render array:

   And any override of responsive-image-formatter.html.twig that renders the link must print link_attributes instead of attributes on the <a>.

5. Minimum core version is now 11.4.

TODO list

• Default configuration for image sizes and styles
• Extend Image formatter
• Extend Responsive image formatter
