Auto Alt Image Meta

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.

How it works

• Scans images when a page is rendered
• Adds ALT and TITLE only if they are missing or empty

• Uses a smart priority system:

  1. Image title (Media Library)
  2. Human-readable filename (if valid)
  3. Post or page title (fallback)
• Ensures unique ALT text when multiple images exist
• Also supports Featured Images
• Makes no database changes

Why this approach is recommended

• No bulk updates required
• No risk of data loss
• Works for old and new content
• SEO-safe and accessibility-friendly
• Plugin can be disabled anytime without leaving permanent changes
