Auto Alt Image Meta automatically improves image accessibility and SEO by adding missing alt and title attributes at render time.

The plugin works instantly after activation and does not require you to update posts or pages. It dynamically injects attributes only when they are missing, ensuring existing manual values are never overwritten.

This approach is lightweight, safe, and matches how professional SEO and accessibility plugins operate.
