Collage help for English: to kill a mockingbird and Macbeth?

Okay, so..I need to make a collage about revenge for english. I've chosen 2 pieces of literature to depict in my collage. The three I chose were To kill a mocking bird and Macbeth. I need to find pictures to represent different examples of revenge in the 2 pieces of literature. Can you find a picture to REPRESENT Bob Ewell's revenge against Atticus, Malcolm coming back to regain his father's throne and when Banquo's ghost shows up to his Banquet causing Macbeth to make a fool of himself in front of his guests? Answers are greatly appreciated, I really need to this help. Thanks!
