How to Output All Attached Images as a Gallery in WordPress

Are you looking for a way to output all of your attachments into an unordered list of thumbnails linking to the full-sized images? While there’s probably a plugin for this, we have created a quick code snippet that you can use to output all attached images as a gallery in WordPress.

Instructions:

All you have to do is add this code to your theme’s single.php file or in a site-specific plugin:

	$args = array(
		'post_type' => 'attachment',
		'post_mime_type' => 'image',
		'numberposts' => -1,
		'post_status' => null,
		'post_parent' => $post->ID
	);
	$attachments = get_posts( $args );
	if ( $attachments ) {
		echo '<ul id="gallery" class="thumbs">';
			foreach ( $attachments as $attachment ) {
			$large_image = wp_get_attachment_image_src($attachment->ID,'large',false);
			echo '<li><a href="' . $large_image[0] . '">'. wp_get_attachment_image( $attachment->ID, 'thumbnail' ) .'</a></li>';
		}
		echo '</ul>';
	}
