There are children in the baptism pictures. There are faces of people who never asked in the convention ones. That is why most church albums never go out.
Three people photographed the same service. The images sit in three phones, a group chat that crushed them, and a USB stick nobody can find.
Visibility belongs to the album. That is what makes the only safe method practical: start private, sort, then publish.
Making an album public is a one-click technical decision. The agreement of the people in the pictures is not a click — and it is your church it commits.
A short list beats a broad promise. Here are both, without rounding.
Create an account, upload a first album privately, and publish it the day the selection suits you.
