Should I send a share link by default?
No. For intimate work, start with client-only access and offer sharing only when the client asks.
How do I handle a request to revoke access?
Use invite-based access so you can disable the invite and reset any passwords without rebuilding the gallery.
Do I need a different gallery for partners?
Not necessarily. You can use a separate invite to the same gallery with its own expiration window so access is controlled.
What should I say in the delivery message?
Keep it simple: who can view, how long access lasts, and how to request changes to sharing.
