Similarly, Web browsers such as Netscape allow you to change the font size of Web pages. And you can reduce the amount of toolbar and the size of the buttons shown on the screen to increase the window display. But remember, the Web pages or presentation slides must follow the same three requirements of outcomes mentioned in the beginning. Make it useful for t hem, not just a prop to make a lecture interesting. If Web pages, or slides for that matter, are heavily laden with graphics, they take a lot of memory both for storage and for loading.
Some people even download and save the pages onto the hard drive before a presentation.
This way you don't need an Internet connection. Of course, you may need to get permission to do this. In the past I have asked authors, told them about the presentation, promised to remove the images from my machine when I was done, and explained how their pages best exemplified the situation I was describing. It's not exactly like being on stage, because you usually don't have a bright spotlight in your eyes completely obscuring your vision. But it might be hard to hold eye contact, and if you're already busy trying to remember everything you wanted to say, you might distance yourself from the audience.
