Hi,
Ran into this problem, after installing Zenphoto on my webhost via simplescripts on bluehost, i looked up a nice theme downloaded it to my computer extracted it and made into a tar, uploaded that to my theme's folder on my webhost and extracted it there.
Now it wont show up in my admin panel but it shows in the theme folder next to the default installed theme's.
Am i doing something wrong ?

Which theme and which Zenphoto version is it? Note that all themes except of the four included standard themes are third party and are not maintained by us. So they might not work correctly.

thanks for the fast reply acrylian, zenphoto version 1.2 [2213].
the theme Highslide JS v.2.0.3

Understand that you dont maintain them, but they should appear as theme option i think ?

What files are there in the theme? There must be either a theme_description.php or a theme.txt file or it will not be recognized as a theme.

a graphics folder and a file named highslide.js

think the extracting gone wrong ?

There should be many more files than that. In addition to the theme description there needs be at least an index.php, album.php, and image.php. Probably there is also a CSS file. So something has gone wrong with the process you used to retrieve the theme and load it to your site.

thanks for taking the time to reply to my 'problem' sbillard
i hope to work it out.
