Email is fine but slow. Easiest way for a large number is cloud storage (Google Drive, Dropbox, One drive etc). Or on Android store photos on SD card, remove and insert into PC reader, very fast that way but only worth it for a large number. Most Android phones will let you plug into PC and see phone as external drive, then copy paste, but this tends to be a bit slower. IPhone needs ITunes, at least installed as it's the only way to get the drivers, you can then use a third party solution such as MediaMonkey.
I find best way to print photos from home is to use the terminals in Max Spielmann, connect phone via wifi or Bluetooth, select photos and print. Saves your expensive printer ink as well....
