This plugin injects Open Graph tags so that WhatsApp/Facebook show a wide (full-width) thumbnail when your links are shared. It prefers the Featured Image at 1200×630, falls back to the first image in content (optional), then to a default URL set in Settings.

== Description ==
- Outputs og:title, og:description, og:url, og:site_name, og:image, og:image:width/height.
- Uses the post Featured Image in a 1200×630 size (wop_og_share). Falls back to full size if not generated.
- Optional: use the first image in post content if no Featured Image exists.
- Optional: set a site-wide default image (recommended 1200×630).

Settings page: **Settings → WhatsApp Preview OG**

== Installation ==
1. Upload the ZIP via **Plugins → Add New → Upload Plugin**.
2. Activate the plugin.
3. (Optional) Set a default image in **Settings → WhatsApp Preview OG**.
4. Ensure posts have Featured Images with at least 1200×630 for best results.
5. Re-scrape with Facebook Sharing Debugger if previews are cached.
