Attachments on posts not working

I am able to upload images and add them to posts, however when theming I see no images:

$args = array(
	            'order'          => 'ASC',
	            'orderby'        => 'menu_order',
	            'post_type'      => 'attachment',
	            'post_parent'    => $post->ID,
	            'post_mime_type' => 'image',
	            'post_status'    => 'any',
	            'numberposts'    => 1,

	        );
	        $attachments = get_posts($args);
	        print_r($attachments);

returns an empty array when used inside the loop. What am I doing wrong?
