Authors use different tools to reach a certain audience. One of these tools is by using an image. For example have you ever noticed how colorful and bright the packaging on brandname cereal is? There are so many different tools on that cereal box like the color, and whats on the box. The box probably has a friendly fun character on the box because that connects to their target audience.

The author will also try to connect with the audence in a more intimate and personal level to get their point across.
