Fancybox doesn't work

In theme I have:

public function Base_Render_Before($Sender) {

$Sender->AddJsFile('jquery.easing-1.3.pack.js');
$Sender->AddJsFile('jquery.fancybox-1.3.4.pack.js');
$Sender->AddJsFile('jquery.mousewheel-3.0.4.pack.js');
$Sender->AddJsFile('jquery.fancybox-gallery.js');
}

It sucessfully includes all the files except jquery.fancybox-gallery.js which is:

jQuery(function($){
$("a#example2").fancybox({
'titleShow' : false,
'transitionIn' : 'elastic',
'transitionOut' : 'elastic',
'easingIn' : 'easeOutBack',
'easingOut' : 'easeInBack'
});
}

I have no idea how to initialize this fancybox..
