We have 3 iPhones in my family. Each phone has been backed up using the same iMac with iTunes. It's been that way for several years now. But my daughter has recently got a new Windows laptop. I downloaded iTunes to her computer so that she could play Apple Music on it. But she's never hooked her phone up to the iTunes on the laptop. But I want to be able to unload photos from her iPhone onto her laptop. Do I need iTunes to do that? If I connect her iPhone to her computer will it link her phone to that version of iTunes? I've never really understood how iTunes works on different computers with 1 phone.
