Great to use as a personal file system. Easy to set up. And actually, the photo upload and auto thumbnailing are as good as any photo album software that I have used. It can be easily customized, easy to use, the code is very clean, dynamic PDF documents, it's really feature rich. Highly recommended. I used it for my photo album software on http://www.togetherwetri.com/photos
And actually, it's up to version 0.6.1 as of this writing - and version 0.6.x is a huge improvement over the previous versions.
