• What it does: Finds an image on the page and inserts the standard Open Graph image tag so previews on Facebook, Twitter and messengers show that image.
• How it works (simple): After the page is rendered it searches for a configured block (by ID), reads the image or srcset inside, converts it to a full URL and adds the og:image metadata to the page head.
• Why it helps: Many sites forget to set the preview image; this plugin fixes that automatically without editing templates or article content.

Quick use note: Install and enable the plugin, set the ID of the element that contains your pages preview image (default: og-image), and enable debug if you want to see what the plugin found during page load.
