Providing information is contextual.

Images instead of text for doing something when all of the information can be conveyed through pictures is generally better. Then the person doesn't need to know what the name of a small part is, it doesn't need to be translated, and that is the primary reason this is how they present safety information for things like airplane passengers.

Mart decisions whether to use text, images, and video is important. Literally everything being one of the three is awful.
