It's a bit less than 552 images and it doesn't take to long.
I already said in the other thread about memo that people shouldn't write down a list and learn it; they should just solve the cube and create a list while doing that, they will learn the images automatically.
And basically the list should consist of words, which come to your mind when you see the pair of letters anyway; you shouldn't create a list with images you would have never thought of, or with images of another person.
The images which come up first in your mind are usually the best.
For multiple bfd I would recommend more than one list anyway...
