How to get photos off iphone5 to laptop?

Can anyone advise please? I have over 1000 photos on my iphone 5. They are all non repalceable and have sentimental value. I'm not very technical minded at all, i don't know how to use itunes, can anyone help? I was told to plug phone into laptop via usb wire, i have not tried it incase my phone gets wiped and deletes everythin.

Via the USB cable, this works with all OS including Windows Classic, XP, Vista, 7 & 8.

Open the "My Documents" tab and look for a list saying iPhone 5, click on it and select the correct corresponding folder.

Your iphone should have usb connector. Plug it in the pc and locate the file of the phone from the pc.
