Click the Exclude button on the right side

My Photo Tab:
On the left side of the screen, you'll see the Included drop-down menu
Click a photo that has a check mark and follow the prompt to remove it.
When you click Remove photo, it's no longer in your book, and it won't have a checkmark in the list on the left.
This photo will now move to Excluded
Good to know: If you delete a photo from the excluded photos, it's permanently deleted and can't be added back.
