[i]why do i have to switch themes?[/i]
That is quite obvious, isn't it? Zenpage is a optional plugin and is not included in the Zenphoto package. That means of course no theme except the zenpage default theme (and efferescence+) features support for it. The extra functions do not add themselves...
If you want to use Zenpage's features you need either to setup your theme to support it or use the standard theme. That's why there is a theming tutorial on the Zenpage project site...
