Answer:
All slides for the multimedia presentation must use an image
Step-by-step explanation:
Images are used to convey the emotion, to illustrate point, or to create dissonance that one can resolve while speaking; so they help the audience to understand and have the full grasp of the material been presented.
Some points are better illustrated with images than texts so using images assist in laying emphasis on a single point because the image has more impact on the human brain than words.
