How could I have overlooked photographorisms? These would be pictures that illustrate sayings. Like a penny going into a piggy back be a photographisms for “A penny saved is a penny earned.” Except it’s not exactly as snappy, is it? Hmmm. True photographisms would be more than a picture, they’d precisely communicate a thought.
And if sayings can be visual how about autographorisms or choreographorisms?
