hi @farroyob
that works well! Exactly what I had in mind.
The only code I had to change was: get_the_post_thumbnail_url instead of the_post_thumbnail_url
the working version:
add_filter( 'wpsl_store_meta', 'custom_store_meta', 10, 2 );
function custom_store_meta( $store_meta, $store_id ) {
$url = get_the_post_thumbnail_url( $store_id, 'medium' );
$store_meta['post_thumbnail_url'] = $url;
return $store_meta;
}
best
