This is the image from the Nuremberg Trials video.

There is a 1945 American film that was made specifically for being screened in the trials and show what the Nazis had done. Around the 9:16, they show the inside of what appear to be a shed with rows upon rows of dead people piled up... and that's where I found the shot. I couldn't find any information online about this specific shot, only the infamous "Bosnia" one from the Game Over screen.
