Assuming it's an LG Smartphone (Android), just plug in the cable from the phone to the USB port of your computer. You may or may not have to tell the phone at this time to mount the drive on your PC. Your PC should then show an extra drive letter or device when you open My Computer (or equivalent if you're not using Windows). Browse through the folders and you'll eventually find photos and videos (probably /DCIM/Camera or the like). Copy as normal.
