OK, I've installed 1.0, created databases, and then uninstalled and deleted databases three times, and each time, I get a different problem.
My current problem: the paths to my images, and the navigation links are both wrong. Take a look:
http://www.lisavollrath.com/zp/
In the admin and on the site, I'm showing a gallery, and my first folder---but the navigation links from the main gallery are missing part of the path, so they're broken. Instead of http://www.lisavollrath.com/zp/albums/Glass/ the navigation is showing up as http://www.lisavollrath.com/zp/Glass/ so I'm getting a 404.
Same with the images. Part of the path is missing, so they're showing up as broken links.
