Updated link for odd no of visible items to highlight middle one

You `unhighlight` function is almost not doing anything. and the selected image should be placed in the middle instead of the left side. — Mehdi Karamosly, Dec 18 '12 at 21:46
this looks a way better, you make the green border even thicker to make it look better. — Mehdi Karamosly, Dec 19 '12 at 17:33

You can get the source of the image by the adding the following:

var src = $(this).children('img').attr('src');

$('#thumbs a').click(function() {
  var src = $(this).children('img').attr('src'); 

  $('#carousel').trigger('slideTo', '#' + this.href.split('#').pop() );
  $('#thumbs a').removeClass('selected');
  $(this).addClass('selected');
  return false;
});

You would do the same thing for the current thumbnail, you would just call the 'src' attr on the thumbnail holder

thanks for reply ; I wanted to highlight and load the current position image on scroll event and not on click of thumbnail ; $(this).children('img').attr('src') gives undefined value – Parag Dec 12 '12 at 08:20

`$(this).children('img')` returns a collection. Even though jQuery selects the first child for you when calling `.attr('src')`, it's not a very clean way to do so. – Robin van Baalen Dec 17 '12 at 13:04
