Boas tenho este código

		$dir = "imagens/galerias/{$cat}";
if ($dh = opendir($dir))
		 {
		   while (($file = readdir($dh)) !== false)
			   {
				if($file !='.' && $file !='..')
				  {
				   echo'
					   <li class="border_fourcol">
						 <a href="'.$dir.'/'.$file.'" title="prettyPhoto"><img src="'.$dir.'/'.$file.'" alt="" /></a>
					   </li>';
	  }
    }
  closedir($dh);
}

Até aqui tudo bem, mas agora gostaria de fazer a paginação destas fotos.

Alguma dica ????

You can't do it, kid. But don't worry, my boy. You're not the only one. No one else can do it.

Algo deste género deve funcionar:

$page = $_GET['page'];
$per_page = 20;
$i = 0;
while (($file = readdir($dh)) !== false)
{
 if($file !='.' && $file !='..') {
   if(((int)($i / $per_page)) == ($page + 1)) {
     echo ...
   }
   $i++;
 }
}

(O código provavelmente tem erros de sintaxe 😄 . Adicionalmente, há pelo menos uma optimização que é conveniente aplicar.)

consegui, ficou assim

			    $cat = isset($_GET['cat']) ? $_GET['cat'] : false;
		    $dir = "images/galerias/{$cat}";

		    if ($cat && file_exists($dir))
		    {

			    // LISTAR FOTOS DAS CATEGORIAS
			    if ($dh = opendir($dir)) // abrir pasta
			    {
				    while (($file = readdir($dh)) !== false) { /
					    if ($file != '.' && $file != '..' && $file != 'thumbs.db') {
						    if (fnmatch('*.jpg', $file)) {

							    $files_array[] = $file;
						    }
					    }
				    }
			    }
			    $count = 0;

			    $limit = 24;

			    $total_pages = ceil(count($files_array) / $limit);

			    $page = (isset($_GET['pagina'])) ? (int)$_GET['pagina'] : 1;

			    if ($page < 1 || $page > $total_pages) $page = 1;

			    $start = ($page - 1) * $limit;

			    echo'<h2>GALERIA: <u>' . strtoupper($cat) . '</u></h2>';
			    echo '<span class="pag">Página: <u>'.$page.'</u> de <strong>'.$total_pages.'</strong></span>
				  <ul class="gallery clearfix">';

				    for ($i = $start; $i < count($files_array); $i ++)
				    {
						 $count ++;
					    echo'<li class="border_fourcol">
							  <a href="' . $dir . '/' . $files_array[$i] . '" title="prettyPhoto"><img src="' . $dir . '/' . $files_array[$i] . '" alt="" /></a>
							 </li>';
					    if ($limit == $count) break;
				    }
			 echo'</ul>';
		   echo '<div class="nav" style="text-align: center;">';
			 if ($page > 1)
			   {
			    echo'<a href="?cat='.$cat.'&pagina='.($page - 1).'"> <img src="images/ant.gif" alt="<<"></a>  ';
			   }
			 if ($total_pages > $page)
			 {
			   echo '<a href="?cat='.$cat.'&pagina='.($page + 1).'"> <img src="images/seg.gif" alt=">>"></a>';
			 }
			    echo'</div>';
		    }
