I have had enough comments and emails on Pictorialis that I feel that I need to clarify what the software is and what it really does.
Pictorialis *does not* require a prior installation of WordPress or any prior knowledge of WordPress. It is a standalone Gallery (like) tool that creates nice looking, well formatted galleries for you without tables or storage in flat files. You *do* require MySql and PHP on your server to be able to run this program.
