Importing Photos Back into the Game

I took some photos of my sims using the phone camera and then I put them into the digital frame from the Moschino pack. I then put the frame into my inventory and moved my sims from one household into a new lot. When I placed the picture frame again, only one image is displayed on it and the inventory is empty. I tried going back a few saves to find the photos before I moved out of the household, but my saves didn't go back far enough ☹️

I still have the photos in my screenshot folder, so is there any way to recover them in the game? Is it possible to import images from file and turn them into in-game photos that can be put into the frame? Thanks for any help!!
