Useful to make your site look more dynamic.
Unlike some other galleries, there is no need to create menu items or any other elements, just type the name of the folder containing images and that’s it, it will show up all images from this folder, one by one in alphabetical order. Also you may type file names separated with comma in filelist argument, to show exact images of selected folder and in exact order.
The “filelist” is very useful because you may add links and titles to your images. Separate images with semicolon and options (image file name, link and title) with commas.
