That a list
be careful if you use my demos because I have extra styles in the directory. back.png should work fine for each folder. You can even define dynamic background where the background is resized to the browser size. you can start with the transparent skin and depending on your background you have to adapt the colors.
low bandwidth should not have anything to do with it (only that you can define in low bandwidth that no backgrounds are used).
TWG checks if the file name looks like a camera name (e.g. DVC-34235.jpg). You can define the number of numbers that are the limit. You can also enter captions on the frontend or by iptc data.
Watermark. You have the clean the cache after changing this (there is a red (!) which tells you this) because cache images are only created once!
create an album
There are 3 ways to create an album. With the TWG Flash Uploaderin the frontend and in the backend and with the TWGxplorer (in the right upper corner where you can create files, folders and twg related files.)
you have to use normal or maximized slideshow if you have an background because the transition effect only works good if the images have the same size (therefore you have this border - where you can define the color in the config). in 1.7.8 I will replace this slideshow mode with one where you can choose beween 10 differend blending modes
you can disable them - search for tips in the config.php
