(Resolvido) Paginação sem banco de dados

Boa Tarde,

O código abaixo funciona perfeitamente na geração das miniaturas e exibição das imagens, porém tentei de várias maneiras, sim pesquisei muito antes de postar para pediar ajuda em um meio de paginar a exibição de imagens. A parte de colunas está ok, porém preciso de auxílio para montar a paginação.

Conto com a colaboração, desde já obrigado.

//gera a galeria
$images_dir = 'imagens/';
$thumbs_dir = 'miniaturas/';
$thumbs_width = 200;
$images_per_row = 4;
 
$image_files = get_files($images_dir);
if(count($image_files)) {
$index = 0;
foreach($image_files as $index=>$file) {
$index++;
$thumbnail_image = $thumbs_dir.$file;
if(!file_exists($thumbnail_image)) {
$extension = get_file_extension($thumbnail_image);
if($extension) {
make_thumb($images_dir.$file,$thumbnail_image,$thumbs_width);
}
}
echo '<div style="width:895px; margin-left:10px;margin:0 auto;text-align:center;"><a href="',$images_dir.$file,'" class="photo-link smoothbox" rel="gallery"><img src="',$thumbnail_image.'" /></a></div>';
 
if($index % $images_per_row == 0) { echo '<div class="clear"></div>'; }
}
echo '<div class="clear"></div>';
}
else {
echo '<p>Nenhuma imagem encontrada</p>';
}
 
?>
