not sure what all you are looking for as an explanation, but the gallery is set up per user. a folder is made when they first create their profile, and all images are placed in it. the thumb vs large image functionality on the user side is a simple javascript snippet.
also, i just finished working on functionality to add folders, where users can add up to 36 images in 3 folders.
i'd like to contribute to some dev on this, my availability is somewhat limited however. been working on music lately, and trying to get a full album together as well shows. plus i've got a few side projects, developing a site and making a theatre module for this theatre company. whowantscaketheatre.com if you feel like checking it out.
anyway, as it progresses, let me know, perhaps i can add something to it..
