Damn yes! That works.
Many thanks.

For those interested, here is the syntax:
[on_this_day title="On this day..." posts_per_page="1" show_post_thumbnail="true" show_post_excerpt="false" show_post_date="true" no_posts_message="Please try again later <img src='https://your domain/wp-content/uploads/Noortje.webp' alt='Smelly Cat' width='500' height='600'>"]

Indeed, that doesn’t work. Tried that before. Too bad. I think it has to be done in the PHP-code.
Maybe it’s an idea to think about an extra parameter (image if no posts) ??
Thanks for the reply
