I have over 5,000 photos on my iPhone and they use less than 1gb of space. How many does she have? What happens to them once she’s taken them - are they sent to someone at the zoo? Can she not delete them as she goes?
One thing I did do was to switch off the automatic storage of photos sent to me via WhatsApp. So I only save other peoples snaps if I want to keep them otherwise I look, comment, and don’t store them as photos. They’re still in WhatsApp if I want to look again.
After photos and WhatsApp, what’s her next digest storage item?
