PowerPoint slides
If you want to do an on-screen presentation from slide presentation software such as Microsoft Powerpoint, you can use your images as well. For Macintosh, the images have to be pict files with 16 bit color or Powerpoint will not recognize them or be able to display them properly. Resolution should be higher than 72 dpi because they will be projected on a large screen. 72 dpi is okay for computer screen presentations but not for projected presentations. We use pictures saved at 350 dpi as pict files. Insert them in the slide. Size them, add text, graphics, etc. These can be used for on screen presentations or sent to a film recorder.
