How do I get the pics?
You have to read through the Spin off "Alice in the World of Wah!".
I've been getting books as slot prizes that say "Alice in the world of wah!" And other stuff but I don't know what to do with them or when to find them once I've accepted them.
Those books unlock some free side stories - Alice in the World of Wah!. If you want to read them, click on "Menu" in the my page and then "Album". There you can see a button for the pictures and one for the stories. Go to the stories and there are all stories that you've unlocked (including the Premium stories in case you bought the Premium Route).
