You can absolutely make a card featuring friends and family. You just need the right permission.
Only upload photos you have the right to use. If a real person is identifiable in a photo, you must have their permission to use their image, and a parent or guardian's permission for anyone under 18.
Please do not upload photos of people who have not agreed, and never use someone's likeness to mislead, embarrass or harass them. See our Acceptable Use Policy for the full rules.
