I'm trying to install the theme 'example' but am unable to get it working. On the theme selection page I have the following message -

Unknown
Unknown
Version Unknown, Unknown
Missing theme info file!

Set Unknown theme options

Also this at the front end -

Zenphoto found no theme scripts. Please check the themes folder of your installation.

I unzipped and uploaded the folder to the Zenphoto themes folder on the server, is there anything else I need to do to tell Zenphoto that it is there?

My fault. I had managed to create a subfolder within the folder. I moved all the files up one level and it now shows.
