Thanks!
The snippet is actually working for the live results, I believe those are the images from the meta field: https://i.imgur.com/skfVBMY.png
For the results page, that is way more difficult, especially with Elementor. I don’t think there is currently a way to add images from URL to the relementor results cards. Elementor does not have a hook for that. I believe the final image HTML code can be altered, but that is not the best approach for a generic solution
I have fixed the issue with the index search, now the missing results should show up.
