Hi Tai,
I've just been testing your site's source code locally, and have modified the css further to get it working with your particular theme and setup.
I've got your albums displaying side-by-side, however, you might want to resize the images to be the same height so they display better.
Just replace the top of hovereffect.css down to the bottom of the "Album Styles Extend" section with the following...
/*
CSS Name: Hovereffect Styles
Description: Hover Stylesheet based on the idea of Hoverbox from http://host.sonspring.com/hoverbox/
Author: Alex Rabe - Orginal by Nathan Smith
Version: 1.60
This is a template stylesheet which doesn't support description below the thumbnails. It's a experimental version.

/* ----------- Album Styles Extend -------------*/
.ngg-albumoverview {
margin-top: 10px;
float: left;
display:inline;
}
.ngg-album {
margin: 5px 10px 5px 5px;
float: left;
display:inline;
}
.ngg-albumtitle {
border-bottom:1px dashed #AAAAAA;
text-align: left;
font-weight: bold;
margin:0px;
padding-bottom: 3px;
font-size: 1.4em;
margin-bottom: 10px;
}
.ngg-thumbnail {
float: left;
background:#EEEEEE none repeat scroll 0% 50%;
border-color:#DDDDDD rgb(187, 187, 187) rgb(170, 170, 170) rgb(204, 204, 204);
border-style:solid;
border-width:1px;
color:inherit;
padding:5px;
}
.ngg-thumbnail img {
filter: alpha(opacity=100);
-moz-opacity: .99;
opacity: .99;
background:#FFFFFF none repeat scroll 0%;
border-color:#AAAAAA rgb(204, 204, 204) rgb(221, 221, 221) rgb(187, 187, 187);
border-style:solid;
border-width:1px;
color:inherit;
padding:2px;
vertical-align:top;
}
.ngg-thumbnail img:hover {
filter: alpha(opacity=90);
-moz-opacity: .9;
opacity: .9;
border-color:#000000;
}
.ngg-description {
text-align:left;
clear:both;
}
Hope this helps!
Cheers,
Mark.
PS. The first place I'd look for the extra Fancybox scripts is in your theme's header.php and footer.php files. If they're added dynamically instead, you'll need to check your functions.php file.
