[Jean le Chauve]

Le 1er gabarit à modifier est dans fancybox, gabarit de galerie, sample :
Attention, j'ai un peu modifié le début et mis en commentaires, il faudra que tu adaptes par rapport au tien

Code :

[== Indéfini ==]
{* In fancybox mode, default template used for listing videos of an album *}
{* HostedVideoAlbums action=breadcrumbs *}
<h2>{$leveltitle}{* $parentobj->name *}</h2>
{* <p>{$parentobj->description}</p> *}
{if $itemcount > 0}
    <div class="gallery">
