  • The automator runs only if the alt text is empty or missing.

Behavior

  • Automatically generates alt text for images without one.
  • Uses AI models to produce meaningful descriptions.
  • Stores the generated alt text in the image field’s alt attribute.
  • Ensures the alt text is non-empty before storing.

Example use cases

  • Automatically describe uploaded images for accessibility.
  • Ensure all content images meet alt text compliance for SEO and screen readers.

Notes

  • The automator does not include explanations in the alt text or expose the prompt output to users.
  • The alt text generated is stored directly in the image field’s data array.
