To make sure your Calendar will be exactly as you want, you can always replace photos! When viewing your Calendar, you can click on button on the right side of your calendar. After clicking on it, just click on the photos with the check-mark to remove them from your Calendar and then click on a picture without the check-mark to add to that page.
