alt_text_bulk_edit

This module provides an interface to review and edit the alternative text of media images in bulk. It is intended for content editors who need to remediate large numbers of media alt text for accessibility.

Bulk edit through the site interface

1. After installing the module, go to Content > Media > Bulk edit alt text (/admin/content/media/alt-text).
2. Rewrite the alt text for as many items as desired, select the checkbox associated with those items, and run "Bulk update alt text on selected media."

Bulk edit through CSV export/import

1. To export a full archive of site media with alt text as a CSV file, go to Content > Media > Bulk edit alt text > Export CSV (/admin/content/media/alt-text/export)
2. Either manually update the alt text in a spreadsheet application, or upload the data into an alt text generating service such as https://alttext.ai.
3. Import the updated CSV at Content > Media > Bulk edit alt text > Import from CSV (/admin/content/media/alt-text/import)

Additional Requirements

This module assumes the use of the Drupal "Media" module. It is not for editing alt text of images uploaded via other means.

Related modules/libraries

Another method for bulk editing alt text is provided by the AI Image Alt Text module, which includes a sub-module, ai_image_bulk_alt_text, for bulk-generating alt text using a pre-configured LLM engine. That approach differs from this module generating alt text is an item by item process, using a button adjacent to individual media items on the editing form.
