Hello sawtellhelp,
It sounds like you had iCloud Photo Library enabled before you reset your phone. You should be able to turn that on in your settings:
How do I turn on iCloud Photo Library?
If you want to turn on iCloud Photo Library on all of your devices, follow these steps:
In iOS 8.3 or later, go to Settings > iCloud > Photos, then turn on iCloud Photo Library.
Thank you for using Apple Support Communities.
