How can I change the default sorting and layout on a Photobook?

Pick Album settings in the photobook's menu under Your photobooks, or at the foot of Edit. Choose the order and layout it opens with and click Save Changes. Visitors can still change both for themselves.

To change several photobooks at once, click Edit All, or Select photobooks and click Edit, then pick Album settings. A field left on Unchanged keeps each photobook's own choice.

Until you choose, a photobook opens by date, oldest first, when most of its photos say when they were taken, and by name otherwise. Date order goes by when each photo was taken, or by the file's date for videos and photos that don't say.

Paid accounts can choose how new photobooks open in their upload defaults.
