[otrs] Customized login screens

Hi , For customer view only i want to customize the login page : ( http://hostname/otrs/customer.pl) I would like to put our company logo (jpg gif format) and remove the standart footer header.. I did manually by editing the text : COMPANY NAME to our company name. But i need more than that. Is there a good editor where i can customize and create a good looking login screen. Our do you have any other suggestions. Regards, Sarper
