It should fit many needs, thanks to its easy installation process and , it can be setup in less than 3 min to put a small photo gallery online. For users with thousands of pictures, don't worry as phpGraphy does use a real directory tree to store the pictures (as you probably already have on your hard-drive), you'll just have to upload your whole picture collection et voila, phpGraphy will generate the thumbnails and low-resolution pictures for you and even better, it can also auto-import IPTC description in the database (if already embeded in your pictures).
