I installed OpenPhoto on our server and we are planning to give access to a bunch of photographers to show their work publicly. Some of their photos will be displayed on our main website.
An admin area would be very useful for me to create new users, reset passwords, and select which photos will show up on our main website.
You only need to create directories if you're storing photos on the local file system or a file system that requires new directories be created (only the local filesystem adapter, as far as I know).
All of our configs are stored in the database so we create a record in the config and user tables.
I know we had an email thread with support@ but I'd suggest starting off with a hosted account on Trovebox. If you have specific concerns then let us know and we'll figure something out.
Yes, a script would be good. is that a script available somewhere?
Is there anything else one should do during setup, like a creating folders or config files?
We don't have plans on adding an admin page to create accounts but it's fairly trivial if you can create all the db records needed. It's what we do at Trovebox - script the creation of accounts.
To select photos to be displayed on a main site you probably want to use the API (though there isn't a meta API that search across accounts).
