Did you mean doing a System Restore, not using the notebook's restore discs which reloads Windows OS? If it's just a System Restore, it shouldn't delete any of your personal files such as photos. However, if you reloaded Windows OS from the restore disks, than in general, it will also reformat the drive. This will make recovering photos more difficult, but not impossible. However, the likelihood of recovering all will be slim.
