I'm not sure yet, but your:
http://www.crocilgator.net/library/js/site.js
is a 404 not found, though I'm not seeing any javascript errors as a result. Also, although in your PHP Photo Album script you have:
Code:
var tempcontainer='<a href="'+imagecompletepath+'" target="'+href_target+'" rel="lightbox[trip]" onClick="return popuplinkfunc(this)">'
which would potentially setup each of these links for initialization via lightbox, if the 'album page' is changed, it will not work. Lightbox 2.04 has a better chance of working with this sort of setup.
If the above hasn't switched on the 'light' for you and you haven't yet figured out the issue(s), perhaps if you were to post a link to another of these installations where it is working, the problem would be more obvious to me.
