Wordpress XML RPC Library To Auto Post

I just need a php library that could work like the following: <?php$wprpc = new WordpressRPC($username, $password, $url);$post_array['post_title'] = "My Post Title";$post_array['body'] = "My post body"; $post_array['pictures'] = array("/home/pics/[login to view URL]","/home/pics/[login to view URL]");$post_array['categories'] = array();//or whatever makes sense.$wprpc->doPost($post_array);
