[Plugin: Nextgen Gallery] Slideshow – how it works?

Hello friends,
I was asked to do some customisation in Nextgen Gallery plugin for some blog.
The requrement was to reduce spaces beteewn images, so different sizes won’t affect it. My solution was to wrap all gallery images into <table>. It solved the request, but completely broked slideshow.
As I learned lately, slideshow uses jQuey “Cycle” plugin to cycle slideshow, and required very specific format like:

<div>
<img …/>
<img …/>
<img …/>
</div>

(It won’t accept my new “tabled” format)
So I need to understand where is the place (in code) where all images are loaded to the slideshow? So I can pass images in corret format.
Thanx for help.
