If you have not used any video, audio or linked files in your  PowerPoint presentation you need only burn the presentation file to your CD-ROM. Scanned images and clipart will be included in the PowerPoint file if they have been embedded and not linked, so you do not need to burn the individual scans or images to CD.

If you have used video, audio or linked files you will have to burn these to the CD. You must ensure that they are burnt on to the CD in the   same relative position to your PowerPoint file as they were on your hard drive.

The easiest way to achieve this, is prior to creating your presentation collect   together in one folder all the video, audio and linked files you are going to   use. Then create your PowerPoint presentation in the same folder, by burning the folder’s complete contents to CD your PowerPoint file will retain its relative   position to your media clips and hence know where to find them.
