The items that you can or cannot personalize in your journal depend on the format you choose.
The layout of the journals is automatic. You can always change the order in which the photos will appear in your journal (more information on this here).
For large photos format (A5)
Each page of the journal consists of a photo, its possible description, the date the photo was added and the name of the contributor. These elements cannot be changed.
On the other hand, the photo printed on the cover can be personalized when creating the journal in the application by choosing your favorite photo and clicking on "Use this photo as cover image".
For small photos size (A4)
Each page of the journal consists of three photos, their possible description and the name of the contributor. These elements cannot be changed.
Cover page photos are chosen at random and cannot be personalized.
