Recover Long gone pictures :(

Hi all ;)
I need help, my husband and I cleaned all of our computers and thought we moved all of our pictures to our large data storage. We missed 6 months of baby pictures that were the only copies. We had them at one point on our laptop with windows 7. We only have 2 restore points that seem to be after the pictures were either deleted or moved off of the laptop. We may, or may not have had to reinstall windows 7 on that laptop, would that prevent me from finding them? I tried Recuva to find them, but it is only showing me pictures and files that are from the past few months. I know the months the pictures were taken but not when they were on the laptop :/
Thank you for your time,
Andrea
