Why is .fadeIn('slow') not working here?
===

I'm trying to make a simple gallery with buttons that allow the user to cycle through images. When the user clicks a button and the image changes, I'd like it to fade in but it doesn't appear to be doing anything? Here is what i have:

    $(function () {
        $("#homeGalleryControls li a").click(function () {
              var image = $(this).attr("rel");
              $('#galleryImage').fadeIn('slow');
              $('#galleryImage').attr("src", image);
              $('.galleryButton').attr("src", "/Content/Images/Design/btn_default.gif");
              $(this).find('img').attr("src", "/Content/Images/Design/btn_checked.gif");
        });
    });

Can anyone see what's wrong here?

Thankyou
