WHY ARE MY PHOTOS NOT SAVING!?!?!?!

Yall I’m about to lose it entirely. I am building a house right now and i have so many photo frames around the house that i have filled with artwork/family photos. I did this days ago. Yet every time i log back in on a new day ALL THE PHOTOS ARE RESET TO THEIR DEFAULT IMAGE. Guys I cant take it anymore. I save my photos i save the materials i make out of them and i save the picture frames! how much more can i possibly save and why is it putting me through this. I am so sick of having to redo every photo every day its getting old and i’m irritated. What am i missing PLEASE!?!?! I’ll add photos if you need to see what im talking about.
