I am trying to make an image change once you scroll to a certain point. I've tried the following but it changes right when you scroll.

    jQuery(function($) {
 $(window).scroll(function() {
   if($('.navbar').hasClass('navbar-brand')) {
     $('.navbar .navbar-brand img').attr('src','http://placehold.it/120?text=Original+Logo!');
   }else{
     $('.navbar .navbar-brand img').attr('src','http://placehold.it/120?text=Original+Logo!');
   }
 });
});

I tried to add the following code for it to know when to switch between images, but failed

    var wn = $(window).scrollTop();
    if(wn > 700){
