There's this option: http://www.zenphoto.org/2008/01/hacks/#zenphoto-as-plugin

or

http://www.zenphoto.org/2008/01/hacks/#external-thumb

Probably the most commonly used is the first one as it allows access to most of the zenphoto functions.

Small addition to the "plugin way": The latest images function is located in the image_album_statistics plugin. So this needs to be include additionally to to the main template-function.php file.
