Defines a field type for image media with supporting, free-form caption and attribution sub-fields.

New Supported image field type extends core's Image field to include Caption and Attribution subfields.
Just like core's Title and Alt subfields, these Caption and Attribution subfields can be toggled on/off and set to required/optional per field instance.
Caption and Attribution are free-form, formatted text fields so users can leverage familiar WYSIWYG tools to create, link, and format content. Achieving different attribution formats as different image sources and licenses may require becomes simple (e.g. "Photo by Author on Source]" vs "Source.com/Author" vs "'Title' by Author is licensed under License").
Allowed text formats is also configurable. This gives you control over what your users can enter into these sub-fields (for example, you could restrict entry to only simple formatting like bold/italic + links).
Default image support: Caption and Attribution content can be configured in the field instance's default image (storage or field-instance level).
Default output uses semantic and elements (default twig template can be overridden if necessary).
Basic views support.
Basic test coverage.
Leaves the core image field type unaltered.

Add and configure a new Supported image field onto a fieldable entity.

None.

Drupal core's Media module
- Introduces a re-usable media entity where an Image (or Supported image) field can be added, along with other fields
- Large contrib ecosystem
- Can add some complexity to authoring permissions (e.g. can user B modify user A's image?)
- Unused media may need manual cleanup
- Can add complexity to content migrations when compared to migrating into a simple Image or Supported image field
- This module is compatible with media, and could be a way of bringing caption and/or attribution into an image media type
Rich Image
- Extends/alters the core image field to add a variety of sub-fields (unaltered core image field is no longer available)
- Sub-fields collected in a new "Rich image properties" fieldset
- Attribution is a plain-text one-liner, so link inclusion might be harder for less technical users
- Caption seems to be a formatted textarea
- Non-configurable help text for caption, attribution, and other subfields
- It appears that the default image's attribution line can be set, but not the caption content
- Small user base, no supported releases, and no test coverage (as of 2025-10)
Image Field Caption
- Extends/alters the core image field to introduce a formatted caption textarea (unaltered core image field is no longer available)
- No dedicated attribution handling
- Non-configurable help text for caption
