You need to make sure that you have space on a page for the image or illustration. However, there is no space on this page, so if you were really giving this talk, you would add one or more pages after Page 4 with illustrations of grids. Clip art is easy to acquire. Many images are included with Freelance Graphics and other sources of clip art may be used. You will have to decide on how appropriate images are for your presentation.
Images are particularly useful if they support or further explain ideas.
Another type of image that may need to be added is an organizational logo. For example, a logo could be added on the title page or to every page in the presentation. Although it may not be important to know much about images when placing them in a word processing document, you do need to be aware of two types of images as you use them in presentations with a color background. They can also be created with a paint program, like the one that ships with Windows 95. Clip art that ships with Freelance is vector images, as are the clip art images from Microsoft's Office and Corel's Suite collections.
