Hi jeanelovesdeano! Yup, we also just submitted photos stuck in A4 and it was ok. Just keep it in chronological order and maybe put some labels on it to help them identify what the pictures are about. I included photos from when we first met to dating, engagement, wedding and our life after. Not sure if they accept albums. Personally I wouldn't want my actual wedding album there there because it's expensive and don't want to risk not having it returned haha. :-)
