Aliciuzz, to post photos, you need to type in your post (caption, where the button is Aa), and then you need to click on the "insert a photo" button to select your photo for Tomodachi Life either on the top or bottom screen.

After you do that, while on the "insert a photo" section, select "Post to Tomodachi Life", and then you're good!
