Retrieve back picture?

Hi, I need help. I know this is just nothing but its really a big deal for me 😅 I took photos long time ago when my sim was a toddler held by her mother arm. The mother was still young adult at that time. I also took photo when my sim that was toddler got married. My sim took photo with his wife on photo studio. My sim also have a photo with his mother, she was elder at that time. My mistake happen when I replace the house with all the pictures hanging on the wall (house on the gallery) without putting it on their inventory. I realize it when I want to place the pictures but it is already too late. I already put what necessary and save it. I have the pictures on the folder though, but is there anyway I can get back to the game? I don’t care what it take, even if there is a mod for it, as long I get back the pictures😂
