GSgallery: Need help from developers - Testing new version

[ronanmagee]

I've tried updating gsgfancybox.php within the plugins folder to reference the updated fancybox code:
/fancybox/jquery.fancybox-1.3.3.pack.js
/fancybox/jquery.easing-1.3.pack.js
/fancybox/jquery.mousewheel-3.0.4.pack.js
/fancybox/jquery.fancybox-1.3.3.css

Having updated this file I'm unsure what other files should be updated to allow me to use this new code. Basically I'm trying to make use of the improved caption option presented here
