I will mark this resolved

Thank you for checking – I think then I’ll leave it as it is, and will be careful with theme updates.

Thank you very much,
and all the best to you,
Moira

Hello Andre,

thanks for your reply. I checked the Rough Pixels page so I was aware of the ownership changes, it’s fully understandable that you are very busy with other things, so I haven’t expected a quick answer :).

Anyway, my wording wasn’t accurate: what I meant was that I’d like to set for each post the post’s featured image, so the side column image would change on each single post page.

Meanwhile, I experimented a bit – if you check my blog https://blog.moirarisenprints.com/ you can see the result. I actually managed to solve it, but what I did is ugly :(…
I wasn’t able to make it work through the functions.php, so I modified the original template-functions.php adding a line for the single posts to the
function custom_background_cb

// background is the custom image or the default image

 if ( is_single() )
{
     $background_image_url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
     }

else     
$background_image_url = set_url_scheme(get_background_image());

// When using a sidecolumn background colour without an image
$colour = get_background_color();

I’m sure it can be done properly with the functions. php, maybe I should remove the original function and add it back with the modifications?

I thought – as the site is working for now as I want it ?? – I will rather wait for your answer.

this is what I tried in the functions.php (child-theme) but it doesn’t do anything

add_action('wp_head', 'featured_custom_background_cb');
  function featured_custom_background_cb()
  {
    if ( is_single() )
    {
         $background_image_url = wp_get_attachment_url( get_post_thumbnail_id($post->ID) );
         }
         return $background_image_url;
  }
