Hi I have page displaying 20 featured images and info of a specific category, I wish to able to have pagination so I can have multiple pages for the category.

How do I do this? I cant seem to get it work.

Any help would be appreciated

Thanks

<?php get_header(); ?>
<div class="modus-grid">
     <?php query_posts(array('category__in' => array(5), 'posts_per_page' => 20)); ?>
            <?php if (have_posts()) : while (have_posts()) : the_post(); ?>

                    <?php $currentid = get_the_id(); ?>

                    <div class="grid-box grid-block mod-box width33">

                        <div class="view view-first">                                
                                <?php if (get_the_post_thumbnail($currentid, array(167, 167)) != "") { ?>

                                   <a href="<?php the_permalink(); ?>" /><?php echo get_the_post_thumbnail($currentid, array(300,600)); ?></a>
                                <?php } else { ?> 
                                    <a href="<?php the_permalink(); ?>" /><img src='<?php bloginfo('template_url') ?>/images/default.png' alt='Default'/></a>
                                <?php } ?>

                            <div class="mask">  
                                <h2><a href="<?php the_permalink(); ?>"><?php echo get_the_title($currentid); ?></a></h2>
                                <p><?php echo get_the_excerpt( $post->parent ); ?></p>
                                <a href="<?php the_permalink(); ?>" class="info">Read More...</a>
                            </div>
                        </div> 
                    </div> 

                    <?php
                endwhile;
            endif;

            wp_reset_query();
            ?> 
            <div class="clearfix">
</div>
<?php get_footer(); ?>

You are not passing any pagination parameters. Like this, from the Codex...

$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$query = new WP_Query( 'paged=' . $paged );

Notice that code uses WP_Query not query_posts. Don't use query_posts. It is pretty much never the best choice for creating a loop.

The top of your Loop should look like...

<?php 
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
$my_query = new WP_Query(array('category__in' => array(5), 'posts_per_page' => 20,'paged'=>$paged)); ?>
    <?php if ($my_query->have_posts()) : while ($my_query->have_posts()) :
         the_post(); ?>

And then the rest of your loop.

You probably also want next_posts_link and previous_posts_link.
