I have installed Zenphoto as a one-click install via my shared hosting and have no FTP access. I have three large albums which i'd like to download, preferably without wget hacks. Is there a way to download albums as zip files from the admin interface without installing extra plugins?

You don't need a plugin but you need to modify the theme used with the needed function printAlbumZip(). There is a tab on the Zenphoto backend to edit theme files. Read the theming tutorial before trying.

Btw, we don't support and recommend one click installs for these and other reasons.

EDIT: My fault I missread the "from admin backend". Sorry you are out of luck, there is no such feature as any proper webspace has ftp access.

OK, thanks. The Dreamhost one click install does not give you access to downloading the files via FTP. I will not use one click install in the future.
