There are too many options:
1. Connect the USB cable between them. The phone becomes a volume in file explorer. Use the computer file manager to copy/move photo files to your computer hard drive. Phone has to be on and open.
2. With the USB cable, use a "helper" app instead of the file explorer.
3. Use Wifi to "Share" folder on the computer and copy files to it with your phone.
4. Use Wifi to "Share" the photo ~DCIM folder on your phone and copy files from it using your computer.
5. If your computer is a laptop and/or has BT, use Bluetooth to connect the phone as in 1, 2, 3, and 4. Bluetooth will be slower than Wifi and USB.
6. Use a OTG USB cable (~$3) to plug a thumb drive into your phone. Copy files to the thumb drive. You can also connect a mouse, keyboard etc to your phone with a USB hub. Include a charger is a good idea.
7. If you have a uSD card in your phone, be sure your photos are stored there. Then temporarily move the card to a reader in your computer.
8. Use an internet drop-box service.
9. Worst solution is email because it may cost you data charges and it will probably convert your pictures to low-res "email compatible" format, and its slow and you can only transfer one or two at a time.
