Iconic images are powerful visual representations that evoke strong emotions or convey significant cultural meanings. They often capture pivotal moments in history, art, or popular culture, making them instantly recognizable. Examples include the photograph of the raising of the American flag on Iwo Jima and the image of the Earth from space. These images can transcend time and geography, becoming symbols of broader ideas or movements. They often serve as reminders of important events, such as Martin Luther King Jr.'s "I Have a Dream" speech, and can inspire social change or collective memory.
