Pagination with custom post type question

Hi,

I’m trying to get a custom post to load on a page but for some reason it seems shows up every other kind of category post apart from the ones I actually want to load.

in functions file the code looks like:

add_action('init', 'gallery_register');

function gallery_register() {

	$labels = array(
		'name' => _x('Photo Gallery', 'post type general name'),
		'singular_name' => _x('Gallery Item', 'post type singular name'),
		'add_new' => _x('Add New', 'gallery item'),
		'add_new_item' => __('Add New Gallery Item'),
		'edit_item' => __('Edit Gallery Item'),
		'new_item' => __('New Gallery Item'),
		'view_item' => __('View Gallery Item'),
		'search_items' => __('Search Gallery'),
		'not_found' =>  __('Nothing found'),
		'not_found_in_trash' => __('Nothing found in Trash'),
		'parent_item_colon' => ''
	);

	$args = array(
		'labels' => $labels,
		'public' => true,
		'publicly_queryable' => true,
		'show_ui' => true,
		'query_var' => true,
		'menu_icon' => get_stylesheet_directory_uri() . '/article16.png',
		'rewrite' => true,
		'capability_type' => 'post',
		'hierarchical' => false,
		'menu_position' => null,
		'supports' => array('title','editor','thumbnail')
	  ); 

	register_post_type( 'gallery' , $args );
}

register_taxonomy("photo_categories", array("gallery"), array("hierarchical" => true, "label" => "Photos Categories", "singular_label" => "Photo", "rewrite" => true));

And on the page I’m trying:

<?php
$paged = (get_query_var('paged')) ? get_query_var('paged') : 1;
	$args = array (
	    'category_name' => $gallery,
		'orderby' => 'date',
		'posts_per_page' => '5'
	  ); query_posts($args . '&paged=' . $paged); ?>

<?php if ( have_posts() ) : while ( have_posts() ) : the_post(); ?>
	<?php
	if ( has_post_thumbnail() ) { // check if the post has a Post Thumbnail assigned to it.
	  the_post_thumbnail();
	}
	?>
    <h2><a href="<?php the_permalink(); ?>" rel="bookmark" title="Permanent Link to <?php the_title_attribute(); ?>"><?php the_title(); ?></a></h2>
<p>by <?php the_author(); ?> on <?php the_time('F j, Y') ?></p>

 <p><?php echo get_the_excerpt(); ?></p>

<?php endwhile; endif; ?>

<?php if(function_exists('wp_pagenavi')) :  wp_pagenavi();  endif; wp_reset_query();?>

The Pagination side of things works it’s showing up the wrong categories?

Anyone have an ides?

Thanks!
