A cord should have come with the phone. If you don't have one, go for inexpensive. One end should be a USB plug, the other will fit into a separate jack or the power jack on your phone. Connect phone to computer. Depending on the software on your phone, you might have to press a few buttons. Other than that if your computer reasonably new you should be able to download the photos into a folder. Think of your phone like an expensive flash drive.

I've emailed photos to myself, too.
