Hey, i have newly setup a installation of zenphoto added a theme and tiny mce and zenpage addon. But i cant figure out how to get my newly added albums to show on frontpage automaticially. Can someone help me ?

Depends what theme you are using. Most included themes do show the toplevel albums on the front page. Sort the album by upload discovery (ID) and the latest will be the first.

If you want to show latest albums from a sub level, you need to use the image_album_statistics plugin and modify your theme to show them.
