iTunes does not find my photos on the PC
Currently using an iPhone 4 but going to upgrade to an iPhone 8. Running iTunes v12.9.0.167 on a up-to-date Windows 7 Pro computer. Downloaded the photos on my iPhone 4 to the computer with the Import Pictures and Videos using Windows option, and checked they were in the default location. So far, so good...
Since I will want to upload my pictures to the iPhone 8, I thought iTunes would enable this through syncing somehow. However, iTunes doesn't seem to recognise my photos, ANYWHERE. Under DEVICES, My iPhone, there is no library of photos, neither does it appear under the main LIBRARY heading.
I tried to 'fool' it into thinking it needed to re-sync, by placing a new photo along with the ones I'd downloaded onto the PC, but despite disconnecting, restarting iTunes, and reconnecting the old iPhone 4, it wouldn't copy over the new picture. I took this to be the fact that iTunes cannot 'see' the photos in the computer.
How am I supposed to copy my photos to the new (to me) iPhone?
iPhone 4, iOS 6.1.3
