Oui oui, c'est bien moi qui avait fait ca....
Peux-tu me redonner le bout de code?

Voila le code pour la 2.0.0:

add_event_handler('loc_end_index', 'direct_jump');

function direct_jump()
{
    global $template, $user, $page;
   
    if (isset($_POST['submit_jump']) and is_numeric($_POST['direct_jump'])) {
   
        $go_to = $user['nb_image_page'] * ($_POST['direct_jump'] - 1);
       
        if ($go_to >= count($page['items'])) {
            $go_to = intval(count($page['items']) / $user['nb_image_page']) * $user['nb_image_page'];
        }
       
        redirect(duplicate_index_url(array(), array('start')) . '/start-' . $go_to);
    }
       
    if (!empty($page['navigation_bar'])) {
        $template->concat('NAV_BAR', '
<br/><br/>
<form method="post" action="">
<div style="text-align:center;">
Aller directement &agrave; la page &nbsp;
<span style="vertical-align:middle;">
<input type="text" size="1" maxlength="2" name="direct_jump"/>
<input class="submit" type="submit" value="Go!" name="submit_jump"/>
</span>
</div>
</form>
');
    }
}
