This is wondeful tools and gives the users freedom to modify it.
This is the most simple gallery module I've ever seen.
However the it is not easy for the user who don't know the HTML to use and it takes times for adding lots of pictures.
Another question if I enable the module, I found it will load the .js and .css files when I open the index pages. Have you tested how large it will be for I don't want to my index page become slow.
