At approximately line 8, after
`# !!! Change this to the absolute path !!!`. This line will read
`RewriteBase /zp`. You'll change it to the absolute path of your ZenPhoto installation directory. For example, if you were to install ZP at http://www.collagestudios.net/photos, then you'll change that line to say
`RewriteBase /photos`. Because I've installed it at http://boison.org/insight, my .htaccess includes the path
`RewriteBase /insight`.
Hope this helps.
