How Do I Transfer Photos from My Photo Library on iPhone to PC?
I tryed through iTunes, nothing. I tryed to open the folder in My Comptuer and only my
Camera Roll pics show.

You have to synch the photos.
Use iCloud
http://www.apple.com/...up/pc.html

or a cable so you can view the pictures on the phone bia windows explorer.

Usually pictures that are in that section were previously synced via a computer/iTunes. That's why they wouldn't be accessible via My Computer/Camera Roll.
