[iMore Question]

My sister has previously transferred photos from her i phone to computer by dragging them between files. If she uses the photos app in the future will every photo on her phone be transferred again or only the new ones, that is the ones that are not already in the computer?

If she is clicking and dragging, there is potential to transfer the old ones. Depending on computer type you should get a file already exist in Windows OS.

I've never synced via transferring that way. A good way to do it is to install iCloud Sync on the computer and all pictures will automatically upload based on preference of connection, cellular data or WiFi.

It depends on whether or not she's transferring the photos manually or not. I mean, if the photos on her iPhone and computer are synced via iCloud then only the newer photos will be added via a sync.
