Excuses my english. It is not my mother tongue.
I have installed Zenphoto in my site. its works correctly. I have disconnect my admin login.
Now, when zenphoto is displayed in my site. I don't see the "admin menu". Also, I cannot to connect in admin menu. The "admin menu" is not here.
What can I do. I see the gallery but not the admin menu.

Thank you very much for your answer.

Zenphoto does not show an admin menu unless there is an admin logged in as it would not be valid to present a administrative menu to the general population.

You can always visit the admin pages: yoursite/zenphoto folder/zp-core/admin.php
