Facebook Login

Hi Guys,

lol facebook login button seems too big for horizontal login module mode. Guys, how can i modify it only text instead of button? I checked code and it fetch login button from somewhere, not sure how can i add only text with that small facebook icon

 <?php if( $params->get('show_facebook_login') && $config->get('oauth.facebook.registration.enabled') && $config->get('registrations.enabled')

								&& (

									($config->get('oauth.facebook.secret') && $config->get( 'oauth.facebook.app' ))

									|| ($config->get('oauth.facebook.jfbconnect.enabled'))

								)

							){ ?>

							<?php echo $facebook->getLoginButton( FRoute::registration( array( 'layout' => 'oauthDialog' , 'client' => 'facebook', 'external' => true ) , false ) ); ?>

						<?php } ?>
