/*  
 * FancyBox popup initialization
 * Nuri Kevenoglu

 Identify and create pop-up images after page fully loads. In your HTML use a rel="galleryX" attribute in your links to mark them as popups, like this:
 <a rel="gallery1" href="full-size-image.jpg" title="Name"><img src="thumb-size-image.jpg" alt="Name" /></a>
 You can group images together using a different numeric suffix in the "gallery" value, e.g. <a rel="gallery25" .. />
 Instead o fimages, you can use any content inside the popup, including flash files. For examples, see http://fancybox.net/
