Hi Hube2,

I tried it out, tied it to the right field key (the one I found with the ‘_field_name’ in the database), but it still does not fill the image field unfortunately. What format should I choose when creating the field? It’s ID at the moment….

All the best

Edit: Just to make sure, I put this into my functions.php, right?

Edit 2: There is a small typo, no ‘ needed after $post_id in line 5. Still not working :D.
