If you don’t want to use a photo in a card, you can remove it from the card page. You can also remove a photo from a card project.
Click the card project in the Source list.
Select the photo that you want to remove.
Press the Control key while you click the photo, and then choose “Remove Photo” from the shortcut menu.
The photo is removed from the photo frame, but remains associated with the card.
Click the card project in the Source list.
Click the Photos button in the toolbar, select the photo’s thumbnail in the Photo pane, and then press Delete.
If the photo was used in the card project, it is removed from the card’s pages, and the photo is no longer associated with the card project.
