Family Sharing question: Do you lose your photos if, as a family member, you upgrade to your family's iCloud storage plan?

My daughter has 50MB iCloud storage and is part of family member sharing in our iCloud account. She has exceeded her 50MB and is about to press the button to join our 2TB iCloud plan. My question: will she lose all of her photos? Or will the photos on her 50MB plan be transferred to the 2TB plan?

Thanks,

Peter
