iTunes will not let you sync your pictures from your iphone to your PC so what you have to do is use explorer to connect to your iphone as a storage device. (just like a flash pen or memory sd card)
You can do it manually as per the video or checkout this free tool – http://www.xilisoft.com/ipod-rip.html
Check out this video for the manual process
