That was a little rushed. This is the final version:


    add_filter('wp_update_attachment_metadata', 'check_size', 10, 2);

    public function check_size($data, $id) {
        if ( $data['width'] < 800 && $data['height'] < 600 ) {
            wp_delete_attachment($id);
            die("<strong class='error'>Error: Image too small</strong>");
        } else
            return $data;
    }
