/* 
 This code creates some layers (overlay, lightbox, etc.) to show images,
 while fading the document viewport.
 
 Code was built upon Lightbox JS, with many modifications by
 Joao Rodrigues for www.atbt.org.br - Jan2009.
 $version 0.3 - 2009-03-30
 
 Inspired by the work of John Resig (jspro.org/files/code/09.zip),
 Peter-Paul Koch (quirksmode.org) and Lokesh Dhakar, creator of
 Lightbox JS: Fullsize Image Overlays 
 - http://huddletogether.com/projects/lightbox 

 Dependencies: atbt102_p.js; lightbox.css; ajax_circle1.gif; and close_20x20.gif
