Check for multiple WordPress attachments

If there is more than one attachment, add a second shortcode parameter:

                <?php
				
				if ( in_category( 'photo' ) ) {
					
					do_shortcode( '[gallery numberposts="1" columns="1" link="attachment"]' );
					//http://wordpress.org/support/topic/if-postpage-has-more-than-one-attachment
					$args = array(
						'post_type' => 'attachment',
						'numberposts' => -1,
						'post_status' => null,
						'post_parent' => $post->ID,
						'post_mime_type' => 'image'
					);
					$attachments = get_posts($args);
					if ($attachments) {
						$c = 0;
						foreach ($attachments as $attachment) {
							if ( wp_attachment_is_image( $attachment->ID ) ) $c++;
						}
						if ( $c > 1 ) {
							do_shortcode( '[gallery numberposts="9" columns="3" offset="1" size="thumbnail"]' );
						}
					}
					
				} else {
					
					the_content('<p class="serif">Read the rest of this entry &raquo;</p>'); 
				
				} ?>

Forgot the echo's before the "do_shortcode".
