how to get photos from my iphone5 to my PC

I have my unlocked iPhone5 connected to my PC via USB cable and I hear an audible ping as it connects, but from the PC side in Windows Explorer I don't see it my Apple phone listed as a device under Computer/Devices. I also looked for it under Control Panel/Hardware and Sound/View devices and printers and not seeing it there either. I just want to move some photos from my phone to my PC... No luck. Any help? I'm running Windows 7 on the PC. On my phone I'm running iOS 7.1.1 (11D201). maybe I should upgrade to iOS 8.1.3, which I've been notified about.
