[Q]Odin'd back to stock lost everything (of course)

Hey guys, I Odin'd back to stock and upgraded to 5.1.1 after having it rooted since root was available. I unfortunately presumed my phones photos were backed up through Google Photos but they weren't. Everything I search requires root so that's not an option. Is there any other options that maybe you guys have from experience that could help me out? Thanks guys and sorry for the long read.
