My LG G4 won't reboot!

AC Question

My LG G4 won't start up again. I have taken the battery out and it freezes on the home screen. I know I can factory reboot BUT I realized I never bought a memory card (don't remember it being offered even!). Will I lose all my pictures?? Is there ANYTHING I can do to save them? ANY chance it is an issue with my battery?

I have 1,000+ pics & several videos saved! I never thought my phone had that much storage!!
