i found a part of the code.
The probleme is i store the year in a variable and when the loop see an other year, it’s erase the year to an other one.

So i get many time the same year and the systeme dont put all the images who have the same year in the same header.

here is my code

<?php 
$post_id = "option"; // options page
$gallery = get_field('galerie_archive', $post_id);

// vars
$order = array();

// populate order
foreach( $gallery as $i => $image ) {
	$order[ $i ] = $image['id'];
}

// multisort
array_multisort( $order, SORT_DESC, $gallery );

// loop through gallery
if( $gallery ): 

$current_header = ''; ?>
        
<?php foreach( $gallery as $i => $image ): 
$date = get_field('date', $image['ID'], false);

$temp_header = date_i18n('Y', strtotime($date));

    if ( $temp_header != $current_header ) {
        $current_header = $temp_header;
        echo "<h3>".$current_header.'</h3>';

    }
        ?>

		<div>
            <img src="<?php echo $image['sizes']['medium']; ?>" alt="<?php echo $image['alt']; ?>" />
            <?php the_field('date', $image['ID']); ?>
        </div>

	<?php endforeach; ?>

<?php endif; ?>
