    "repositories": [
    {
      "type": "vcs",
      "url": "https://github.com/purplespider/GridFieldBulkEditingTools"
    }
  ],

Then install this module:

composer require purplespider/silverstripe-basic-gallery-extension ^4

v3 Upgrade Notes

Upgrading to v3 will break existing galleries due to a change to a polymorphic relation, to fix:

1. Run dev/build
2. Run /dev/tasks/upgrade-basic-galleries script.

Config

The Extension can be applied to any page type to enable the gallery functionality.

You can also customise the CMS tab that the gallery appears on, as well as the title of the gallery displayed in the CMS, and rename the main Content tab:

---
Name: custom-basic-gallery-extension
After: basic-gallery-extension
---
HomePage:
    extensions:
        - PurpleSpider\BasicGalleryExtension\PhotoGalleryExtension
    gallery-title: Image Gallery
    gallery-cms-tab: Main
    content-cms-tab: Top Content

Automatically Delete Image Files

To automatically delete image files when an image is deleted from a gallery:

---
Name: custom-basic-gallery-extension
After: basic-gallery-extension
---
PurpleSpider\BasicGalleryExtension\PhotoGalleryImage:
    ondelete_delete_image_files: true

This uses Delete Asset If Unused Extension to detect if the image is being used elsewhere on the site, and will only delete it if it isn't. There are caveats though, so check this module's readme, i.e. you might not want to use this on sites that have been upgraded from Silverstripe 3.
