Fancybox Show alt or title

I would like to have my alt and/or title tags displayed in the fancybox overlay.

I found fancybox settings in the /scripts/jquery.custom.js
Starting at row 437 – I changed

	if(jQuery().fancybox) {
			jQuery("a.fancybox").fancybox({
				'transitionIn'	:	'fade',
				'transitionOut'	:	'fade',
				'speedIn'		:	300, 
				'speedOut'		:	300, 
				'overlayShow'	:	true,
				'autoScale'		:	true,
				'titleShow'		: 	false,
				'margin'		: 	10
			});
			
			jQuery("a.fancy-iframe").fancybox({
				'type'			: 'iframe'
			});
	}

to

	if(jQuery().fancybox) {
			jQuery("a.fancybox").fancybox({
				'transitionIn'	:	'fade',
				'transitionOut'	:	'fade',
				'speedIn'		:	300, 
				'speedOut'		:	300, 
				'overlayShow'	:	true,
				'autoScale'		:	true,
				'titleShow'		: 	true,
				'titlePosition'	: 	'over',
				'margin'		: 	10
			});
			
			jQuery("a.fancy-iframe").fancybox({
				'type'			: 'iframe'
			});
	}

but there is still no title displayed.
I do have a custom function to add the class=”fancybox” to all my images, so I don’t need to do it manually when adding images.

Hope you can help.
