Thanks Chris, I tried adding the script but it just either fails to open the fancybox OR sends me straight to the Youtube site. I’m stuck. Could you point me in the right direction? Maybe some other buyer has already done this??? I need a mixture of pictures and video in my portfolio. I appreciate any help. Thanks again 
$(“single_video”).click(function() { $.fancybox({ ‘padding’ : 0, ‘autoScale’ : false, ‘transitionIn’ : ‘none’, ‘transitionOut’ : ‘none’, ‘title’ : this.title, ‘width’ : 680, ‘height’ : 495, ‘href’ : this.href.replace(new RegExp(“watch\\?v=”, “i”), ‘v/’), ‘type’ : ‘swf’, ‘swf’ : { ‘wmode’ : ‘transparent’, ‘allowfullscreen’ : ‘true’ } }); });
return false;

From the looks of your code your selector is incorrect.
This:
$(“single_video”)Needs to be a class .ie:
$(“.single_video”)Also make sure to check out this page: http://fancybox.net/howto on the details of using an iframe to show a video.
Thanks
