Configuration of Gallery and administration of the photo albums is done entirely via an intuitive, web interface. You don't need special privileges on your webserver to install, configure and maintain Gallery.
I tested this too years back, easy to use, simple interface, It does not work on GD which is with php. Image Magick or NetPBM must be available at host for Gallery. Some Lamp hosts have these. - SAN Gear
