No security coverage
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
- Go to Configuration → Media → AltTextLab Settings and add your AltTextLab API key.
- Choose the model style and output language, and decide whether the site is publicly reachable (public URLs) or should send images as base64.
- Optionally enable “Auto-generate alt text for new media items” to fill alt text on upload.
- Use Reports → AltTextLab Dashboard to verify API status/credits.
- 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.
- 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.
