How to move photos from my pc to my iPhone ( its windows 8.1)?

Added (1). there are lots of photos

Upload them to your email account and use your phone to download them.

You get the phone charger and plug it into the laptop

There are many ways. Either by syncing or by bluetooth or using dropbox or one drive etc

First of all you should upgrade your PC to Windows 10, 8.1 is fine but Windows 10 is the best around, and it's free, once done that just sell that stupid toy of yours called iPhone and buy a better phone like a Lumia 950 or Lumia 930
