Retrieving Norton Ghost 15 Backups without Norton Ghost

Ghost 15/Win 7 created Files and Folders and System Images for me on an external Passport Drive.

 

Motherboard on the Win 7 PC crumped.  Bought new PC that had Win 8.  Ghost 15 not compatible with Win 8.

 

How do I get my Win 7 data, currently contained in Ghost 15 Files and Folders backup folders, into the Win 8 PC?

 

Someone has suggested acquiring Norton Online Backup ("Set-It and Forget-it File and Photo Backup") for $29.00.  If I uploaded NORTON files through this service, could I fetch the files as unencrypted ready to use Windows compatible data files?

 

Would like something simple and not any more expense than needed.
