Yes, you can add multiple photos, but you have to select a card template with multiple photos (on the mobile / tablet) or add the additional images in the layout editor (this is only possible on the PC or laptop). You can also choose a template from our "Create your own" option, available under each category, and you can add and place your own photos and text as you like.
Please also note that if you want to customise an existing template, we cannot change the entire design of the template (eg insert or remove decorative picture frames).
