The Yoast SEO module for Drupal displays the warning:
Bad SEO score
"No images appear in this page, consider adding some as appropriate". Even when a valid tag is present in the content body (or the field configured for content analysis).
1. Use Drupal 10 or 11
2. Ensure the Yoast SEO module is installed and configured correctly.
3. Edit a content node using a WYSIWYG editor (e.g., CKEditor 5).
4. Insert an image into the body field(field_body) via the editor (ensuring the image renders as a proper tag in HTML).
5. Save the content and observe the Yoast SEO analysis output.
Yoast should detect the image and not show the “No images appear in this page” warning.
Yoast incorrectly reports that no images are found, resulting in a bad SEO score, even though the image appears correctly in the rendered HTML.

Code
The issue was with the widget settings in the form display.
I have to select a view mode that has all the fields, including the image, so it can analyse the contents of the page.
In my case, it was "default", which was empty, and I use "full" view display mode, which fixed the problem.
