Slide shows are another method for delivering multimedia on the Web. In a slide show, you synchronize audio with still images. Through this approach you provide information via audio and add visual emphasis with still images. As an example, to present the training video mentioned above as a slide show, you would use video editing software to synchronize the narration with still images of the weighing and measuring procedure. Still images compress much more efficiently than video, and because slide shows do not require smooth motion, the movie frame rate can be low. This in turn means that you can devote more data to image quality and size.
