Hopefully, you've found this chapter extremely useful and are well on your way to mastering the techniques described previously. We've looked at the differences between raster and vector imagery, where to find the best images, and also how to create your own that work in the best way possible for a Prezi presentation.

Raster images are simply made up of pixels, while vector images use lines or curves. This means that when you zoom in on a raster image, the image will appear blurry. A vector image, on the other hand, will look sharp no matter how closely you zoom in. When using a presentation tool such as Prezi, which focuses heavily on the use of zoom, it's important to make sure that your images look sharp!

Although it might be easier to only use vector images initially, sometimes all we have that will work is a raster image. In this case, we reviewed several ways that we can convert those raster images into vector images.

Remember, though, that business presentations need to deliver important messages on time and as effectively as possible. With this in mind, it's crucial that you decide just how much time you're going to spend on imagery when you also need to consider other important factors and probably juggle other projects. Give yourself enough time and do Prezi the justice it deserves to really make an impact in your business presentations. Don't rely on the fact that people will be wowed by the zooming and spinning if they haven't seen Prezi before. This won't last long and certainly won't deliver your message any more clearly. Make sure you project the right image.

Now that you've mastered imagery in Prezi, it's time to look at using sound as well. The skills you've learned in this chapter will help the visual learners in your audience understand your presentation, but what about the auditory learners in the crowd who need a little extra help?

In Chapter 6, Using Audio, we'll address the use of audio in Prezi. Whether you're standing in front of an audience and presenting or embedding your Prezi into a website for people to explore online and in their own time, sound can really help.
