code source d'un script

Bonsoir,

J'essaye d'intégrer sur mon site, un script pour afficher des photos, et les photos sont dans des dossiers par thème, comme dossier1, dossier2, dossier3. Le script est en php. Etant débutant en php, je bute sur un bout de code : <a href="<?php echo $_SERVER['PHP_SELF']; ?>"

voici le code en entier :

<?php
/***** gallery settings *****/
$mainFolder = 'albums'; // main folder that holds subfolders - this folder resides on root directory of your domain
$no_thumb = 'foliogallery/noimg.png'; // show this when no thumbnail exists
$extensions = array(".jpg",".png",".gif",".JPG",".PNG",".GIF"); // allowed extensions in photo gallery
$itemsPerPage = '12'; // number of images per page if not already specified in ajax mode
$thumb_width = '150'; // width of thumbnails
$sort_by = 'date'; // 'date' will sort albums by upload date - change 'date' to anything else to sort by album name
$show_caption = 'yes'; // 'yes' will display file names as captions on each thumb inside albums
/***** end gallery settings *****/

$numPerPage = (!empty($_REQUEST['numperpage']) ? (int)$_REQUEST['numperpage'] : $itemsPerPage);
$fullAlbum = (!empty($_REQUEST['fullalbum']) ? 1 : 0);

// function to create thumbnails from images
function make_thumb($folder,$src,$dest,$thumb_width) {

$ext = strrchr($src, '.');
$ext = strtolower($ext);

switch($ext)
{
case ".jpeg":
$source_image = imagecreatefromjpeg($folder.'/'.$src);
break;

case ".jpg":
$source_image = imagecreatefromjpeg($folder.'/'.$src);
break;

case ".png":
$source_image = imagecreatefrompng($folder.'/'.$src);
break;

case ".gif":
$source_image = imagecreatefromgif($folder.'/'.$src);
break;
}

$width = imagesx($source_image);
$height = imagesy($source_image);
$thumb_height = floor($height*($thumb_width/$width));

$virtual_image = imagecreatetruecolor($thumb_width,$thumb_height);

imagecopyresampled($virtual_image,$source_image,0,0,0,0,$thumb_width,$thumb_height,$width,$height);

imagejpeg($virtual_image,$dest,100);
imagedestroy($virtual_image);
imagedestroy($source_image);

}

// display pagination
function paginateAlbum($numPages,$urlVars,$alb,$currentPage) {

$html = '';

if ($numPages > 1)
{

   $html .= 'Page '.$currentPage.' of '.$numPages;
   $html .= '   ';

if ($currentPage > 1)
   {
   $prevPage = $currentPage - 1;
   $html .= '<a class="pag" rel="'.$alb.'" rev="'.$prevPage.'" href="?'.$urlVars.'p='.$prevPage.'">««</a> ';
   }

   for( $i=0; $i < $numPages; $i++ )
   {
$p = $i + 1;

   if ($p == $currentPage)
   {
   $class = 'current-paginate';
   }
   else
   {
   $class = 'paginate';
   }

   $html .= '<a rel="'.$alb.'" rev="'.$p.'" class="'.$class.' pag" href="?'.$urlVars.'p='.$p.'">'.$p.'</a>';
   }

   if ($currentPage != $numPages)
   {
$nextPage = $currentPage + 1;
   $html .= ' <a class="pag" rel="'.$alb.'" rev="'.$nextPage.'" href="?'.$urlVars.'p='.$nextPage.'">»»</a>';
   }

}

return $html;

}
?>

En affichant le code de la page, j'ai comme ceci :

<link rel="stylesheet" type="text/css" href="galerie/foliogallery.css" />
<link rel="stylesheet" type="text/css" href="galerie/colorbox/colorbox.css" />
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.1/jquery.min.js"></script>
<script type="text/javascript" src="galerie/colorbox/jquery.colorbox-min.js"></script>

<script type="text/javascript">
$(document).ready(function(){
// initiate colorbox
$(".albumpix").colorbox({rel:'albumpix', maxWidth:'98%', maxHeight:'98%', slideshow:true, slideshowSpeed:3500, slideshowAuto:false});
});
</script>

<div class="fg">
<div class="titlebar">
<span class="title">Galeries Photos</span> - 5 albums
</div>

<div class="clear"></div>
<div class="thumb-wrapper">
<div class="thumb">
   <a class="showAlb" rel="Big Bear California" href="/smockarate/index.php?album=Big+Bear+California">
   <img src="galerie/albums/Big Bear California/thumbs/pict6.jpg" width="150" alt="Big Bear California" />
   </a>
</div>
<div class="caption">Big Bear California</div>
</div>

Et quand je clique sur le dossier des photos, au lieu d'afficher l'album de photos, il me redirige vers la page d'accueil du site, et regardant de près, j'ai vu href="smockarate/index.php?album au lieu de gallery.php?album et le localhost ne fait pas partie. Je test ce script en local avec Easyphp 5.3.8.1.

Ma question est : comment faire pour que ce script détecte le localhost.
Merci de votre aide.
