If you only think about how to upload the photos in the gallery, it is easy.
And the files you have uploded work just file as a gallery... then..
TWG is made to make it quick and easy:
You upload pictures to the folder named /pictures.
There you can add subfolders, each subfolder would be like a subgallery in the mail gallery.
In the "How to" you can read how do more... like passwordprotect a subfolder, make a spesual image for a subfolder and much more...
Take a look in my gallery, there i have used most of the options in the gallery.
