AltTextLab adds AI-powered alternative text to your Drupal media library. It can auto-fill alt text on upload and bulk-generate captions for existing images.

Features

  • Automatic alt text generation on new image uploads.
  • One-click bulk generation for all media images or a selected set from the Media Library, with queue processing and progress tracking.
  • Configurable AI model style and output language; supports both public URLs and private sites via base64 upload.

Post-Installation

  1. Go to Configuration → Media → AltTextLab Settings and add your AltTextLab API key.
  2. Choose the model style and output language, and decide whether the site is publicly reachable (public URLs) or should send images as base64.
  3. Optionally enable “Auto-generate alt text for new media items” to fill alt text on upload.
  4. Use Reports → AltTextLab Dashboard to verify API status/credits.
  5. For backfill, open Configuration → Media → AltTextLab Bulk Generation to run across all media, or select items in Media Library and choose “Generate alt text” to process a subset. Bulk jobs run via Drupal’s queue/cron; keep cron running until complete.
  6. Review results in Reports → AltTextLab History (success, failed, and bulk tabs) and apply generated text to media items as needed.

Additional Requirements

  • AltTextLab API key and active credits/subscription.
  • Outbound HTTPS access to https://app.alttextlab.com
  • Drupal core (Media) and cron/queue processing enabled for bulk runs.
  • PHP 8.0+.

Recommended modules/libraries

  • Core Media and Media Library.
  • Automated cron or a queue runner to keep bulk jobs moving.
