Bon
j'ai décidé de passer par javascript mais en plus simple :
donc le gabarit :

Code :

<div id="grande">
{foreach from=$images item=image}
<blockquote style="display:none" class="photos_grande" id="{$image->fileid}"><img src="{$image->file|escape:'url'|replace:'%2F':'/'}" alt="{$image->titlename}" width="640" /></br>
<h4>{$image->titlename}</h4>
{$image->fields.vrai_commentaire.value}</blockquote>
{/foreach}
</div>
<div id="miniatures">
{foreach from=$images item=image}
<a href="#grande" onClick="affiche('{$image->fileid}')">
<img src="{$image->thumb|escape:'url'|replace:'%2F':'/'}" alt="{$image->titlename}" />
</a>
{/foreach}
</div>

le css

Code :

.gallery .img {
    height: 120px;
    /*width: 120px;*/
    float: left;
    margin: 10px;
    text-align: center;
}

.gallery .img a {
    display: inline-block;
    border: 2px solid #ddd;
    padding: 1px;
}

.gallery .img a:hover {
    border-color: #999;
}

.gallery img {
    border: none;
}

.gallery .pagenavigation {
    height: 50px;
}

.gallery .prevpage a, .gallery .prevpage em {
    display: block;
    width: 50px;
    height: 39px;
    float: left;
    margin: 0;
    text-indent: -1000px;
    background: url(../../images/previous.png) transparent no-repeat 0 0;
}

.gallery .nextpage a, .gallery .nextpage em {
    display: block;
    width: 50px;
    height: 39px;
    float: left;
    margin: 0 6px 0 0;
    text-indent: -1000px;
    background: url(../../images/next.png) transparent no-repeat 0 0;
}

.gallery .parentlink a {
    display: block;
    width: 50px;
    height: 39px;
    float: left;
    text-indent: -1000px;
    background: url(../../images/uppage.png) transparent no-repeat 0 0;
}

.gallery .pagenavigation a:hover {
    background-position: 0 -40px;
}

.gallery .prevpage em, .gallery .nextpage em {
    background-position: 0 -80px;
}

.gallery .pagelinks {
    float: right;
    border-right: 2px solid #666;
}

.gallery .pagelinks a, .gallery .pagelinks em {
    margin-top: 6px;
    padding: 0 6px;
    border-left: 2px solid #666;
    text-align: center;
    font: bold 11px verdana; color: #666;
}

.gallery .pagelinks em {
    color: #000;
}

.galleryclear {
    clear: both;
}


/* LIGHTBOX */

#lightbox{    position: absolute;    left: 0; width: 100%; z-index: 100; text-align: center; line-height: 0;}
#lightbox img{ width: auto; height: auto;}
#lightbox a img{ border: none; }

#outerImageContainer{ position: relative; background-color: #fff; width: 250px; height: 250px; margin: 0 auto; }
#imageContainer{ padding: 10px; }

#loading{ position: absolute; top: 40%; left: 0%; height: 25%; width: 100%; text-align: center; line-height: 0; }
#hoverNav{ position: absolute; top: 0; left: 0; height: 100%; width: 100%; z-index: 10; }
#imageContainer>#hoverNav{ left: 0;}
#hoverNav a{ outline: none;}

#prevLink, #nextLink{ width: 49%; height: 100%; background-image: url(data:image/gif;base64,AAAA); /* Trick IE into showing hover */ display: block; }
#prevLink { left: 0; float: left;}
#nextLink { right: 0; float: right;}
#prevLink:hover, #prevLink:visited:hover { background: url(../lightbox/images/prevlabel.gif) left 15% no-repeat; }
#nextLink:hover, #nextLink:visited:hover { background: url(../lightbox/images/nextlabel.gif) right 15% no-repeat; }

#imageDataContainer{ font: 10px Verdana, Helvetica, sans-serif; background-color: #fff; margin: 0 auto; line-height: 1.4em; overflow: auto; width: 100%    ; }

#imageData{    padding:0 10px; color: #666; }
#imageData #imageDetails{ width: 70%; float: left; text-align: left; }    
#imageData #caption{ font-weight: bold;    }
#imageData #numberDisplay{ display: block; clear: left; padding-bottom: 1.0em;    }            
#imageData #bottomNavClose{ width: 66px; float: right;  padding-bottom: 0.7em; outline: none;}         

#overlay{ position: absolute; top: 0; left: 0; z-index: 90; width: 100%; height: 500px; background-color: #000; }

et c'est là le problème le javascript:

Code :

<script type="text/javascript">
function affiche(photo_id){
var zones = document.getElementsByTagName("blockquote");
for (zone in zones){
zones[zone].style.display = "none";
}
document.getElementById(photo_id).style.display="block";
}
</script>

Tout ce qui est après la boucle for ne fonctionne pas, si j'enlève la boucle la photos apparait bien, la boucle sert à cacher les grandes photos déjà affichées pour en avoir qu'une seule.
Je comprends pas pourquoi le script ne va pas plus loin que la boucle...
