Have you ever been in a car accident? What time of day was it (day or night)? Who was driving? Where did it occur? I bet if it was 20 years ago you could still answer these questions quickly but you may not be able to tell me where you drove last Tuesday. Why? Action and emotion. If something has action it will stay in your memory for 20 years. If there is no action you may not recall it in 20 minutes.
So let’s say the name is Steve (your image is stove) and he has a big nose (your file) then with vivid action and emotion you imagine a stove cooking his nose. If the name is Lisa (your image is Mona Lisa) and she has pretty eyes (your file) then with vivid action see the Mona Lisa being painted in her eyes.
