Adding a Next/Prev that moves images in a "carousel" fasion.

Adding a Next/Prev that moves images in a "carousel" fasion.

We have a lightbox slider on our website, and it contains a little carousel at the bottom with clickable images. When you click one, it displays larger in the center of the lightbox. 

I'm trying to add next/prev actions to the thumbnail carousel slider, so that a user can click next, and see 5 more thumbnails they could potentially click on.. if that makes sense. 

Right now the script tied to the carousel is 

  2. /**
  3.  * Set the gallery thumbnails
  4.  */
  5. (function($)
  6. {
  7. $.fn.setThumbnailData = function( gallery_id, photo_id )
  8. {
  9. // The data we're working with
  10. var data = suprflickr[gallery_id].photos;

  13. // The string to set
  14. var str = "";
  15. for ( p in data )
  16. {
  17. if (photo_id == data[p].id)
  18. str += "<a href='#' gallery_id='" + gallery_id + "' photo_id='" + data[p].id + "' class='thumb current'>";
  19. else
  20. str += "<a href='#' gallery_id='" + gallery_id + "' photo_id='" + data[p].id + "' class='thumb'>";
  21. str += "<span class='img'><img src='" + data[p].url_sq + "' /></span>";
  22. str += "</a>";
  23. }
  26. // Set the content
  27. $(this).find('.slider').html( str );
  30. // Set the actions on the thumbnails
  31. $(this).find('.thumb').unbind('click').click(function()
  32. {
  33. var t = $('#suprflickrGallery .list .content a[photo_id="' + $(this).attr('photo_id') + '"]');
  34. $('#suprflickrLB').setLightboxData($(t), 'fade');
  35. $('#suprflickrGallery .list .content a.current').removeClass('current');
  36. $(this).addClass('current');
  37. $(t).addClass('current');
  38. $(this).parent().setThumbnailSliderPosition();
  39. return false;
  40. });
  43. // Set the width of the thumbnail container
  44. $(this).find('.slider').setThumbnailSliderPosition();
  45. }
  46. })(jQuery);
You can see the example here :  http://d.perich.com/grand-hotel/2013/index.php/named-rooms#72157623652852736&7160479178

Any help would be greatly appreciated.
