If you own an office suite from one of the big three, you will have a slide presentation program included. For creating the slides, you can use BMPs, PICTs, TIFFs, JPEGs, and GIFs. Add AVI, MPEG, or QuickTime movies, or recorded sounds to each slide.
Record sounds or voiceovers to play when a selected slide is displayed.
I found it easy to add a WAV or MIDI file to a slide. Create an overlay or attach an AVI, MPEG or QuickTime movies to play when a selected slide is displayed. If you have a digital camera or scanner you can hook them up and take the image directly into the program. It will also let you enhance the image. Functions include Brightness, Contrast, Hue, Crop, Zoom and Rotation.
