Add ability to display the title or alt as caption for thumbnails as well

I can add the caption for the main image, but when using a carousel as the pager, it would be super-awesome to be able to display the alt or title as a caption for each thumbnail. If this is already available, please let me know how to do this. It seems like it would be a pretty simple change since the alt and title are already rendered in the markup for each thumbnail.

A simple jQuery snippet does the trick, but would be a nice user config option.

$('.jcarousel-item img[title]').each(function(){
  var title = $(this).attr('title');
  $(this).after('<div class="carousel-img-title">' + title + '</div>');
});

Something like that.
