Can i more photos stored in system preferences

I don't know what i did other than run the Norton Clean, and my  photos are all deleted, except somehow landed in the system preferences folder in the desktop/screensaver app.  Can i access those photos somehow to move them into another folder or desktop anywhere except the system preferences app?  I ran the "Clean" option months ago, thought photos were gone forever, but just now see them in that systems preferences app....   

Thanks in advance if anyone can help, keep in mind I am obviously not computer savvy.

FYI i have the Mac book pro with the new Big Sur version Norton 360
