Sure, you could include just talk about the Principles of Ethical Conduct, and show a text-only slide of them. Isn’t it more effective to include a picture of a printout of the Principles?
“But no one in the audience can read the tiny print on the picture?” Right. It doesn’t matter. You’ll quote (or probably even better, paraphrase them, as in this slide from NASA. The point of the picture is to add visual interest. It also subtly enhances the presenter’s credibility. You are not just standing in front of the group making things up.”Seeing is believing,” right?
Here’s a copy of this slide you can insert into your own slide show. Lots more on the importance of using graphics later.
