Hi Linnea. I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.
When you chose not to save files during the Reset unfortunately it deleted them, so the only option now is to use Data Recovery software which almost never works if the drive has been formatted over which it has. But you can try it starting with Recuva which is will let you know if the pictures can be recovered: http://www.piriform.com/recuva/features.
There is also no Go back to old Version after a Reset, only after a Version Update for a limited time of approx 10 days.
I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
