It is called Gallery
and is located at http://www.menalto.com/projects/gallery/index.php
Actually I put the files in a directory on my site, and then pointed the script at those files, and it worked.
However I now have other problems.
Since I am extremely new to PHP, and I know that recently Dreamhost changed somethings dealing with PHP, I am wondering if the errors I am getting are from the changes, or if I have done something wrong. It is frustrating because I have a place to go for FAQ and for threads of discussion, but it takes hours and hours of reading to find out answers to small issues.
I have to get the script to recreate the errors before I can post them, so I have to go back through the set up to have it do it. If you try to install the script by some chance, let me know what you find. I am getting errors about not being able to write to files and access denied sort of stuff.
