I've modified TinyWebGallery program, that's running on Pupko.com to allow for slideshows in galleries (previously you had to go into a particular image first, for some reason), and to allow for gallery "summaries" (viewing a particular gallery's 20 mid-sized pictures at a time, as opposed to image by image or small thumbnails). Let me know how you like it... I will post the tutorial on how to do that on the website fairly soon, I hope.
Additionally, I would like to thank IconBuffet for the cool penguin icons that I used :)
