"Adding the visual dimension to a document or speech can be an excellent way to hold your audience’s interest and make your meaning clear. But be careful not to get carried away. Perhaps the most important rule to remember in using visuals is this: the visuals are to support your document or presentation, not to take the place of it. A picture may be worth a thousand words, but it is the words that really count. Make sure that your communication is researched, organized, and presented well enough to stand on its own. Whatever visuals you choose should be clearly associated with your verbal content,repeating, reinforcing, or extending the scope of your message."
