To the cover of one of my christening books, these can be leather, silk or in the photo below, buckram and I can also include a debossed photo on the front cover.
A good idea for the inside front page is to include the christening invitation.
Images on pages can fill the page to leave no border.
Or a single image can be laid out with a generous border
Two images can look terrific.
It can be fun having a 'lead' image with smaller images to the left.
Smaller images can also be placed to the right of the 'lead' image.
Or the smaller images can be below the 'lead' image.
In summary, when I design my books, I consider whether images 'belong' together, their significance and if there is sufficient difference between the pages to make them visually interesting to the viewer.
