Hi @elliot, thanks for reply again.
So just a thought.
$images = get_field('gallery-field', $post->ID);
if( $images ):
foreach( $images as $image ):
echo '<li style="text-align:center !important;">';
echo '<a href="'.get_permalink($post->ID).'">';
echo '<img src="'.$image['sizes']['large'].'" alt="'.$img_alt.'" />';
echo '</a>';
echo '</li>';
endforeach;
endif;
This form would be the correct way? For that he pull the first image from the Gallery in multsite?
$image['sizes']['large']
