Enable the marketplace storefront
Turn on prints + albums + wall art per gallery.
On the gallery edit page, toggle Store enabled. The client sees /g/<id>/store with products from every active marketplace partner: real labs (WHCC, Madera, etc.), albums, and your local shop.
Pictage takes a per-partner fee from each order. The photographer gets the remainder. See your Earnings dashboard for the running total.
If you've added a local shop partner, marketplace_partners.config.contact_email gets a one-click confirm email on every order.
