    Digital Images in PowerPoint (PowerPoint 97)

    I have a user who is trying to put 60 images in a presentation. The slides will contain one image each and little or no text. They are using GIFs converted to JPGs. I do not know the range of sizes. The presentation file is huge.

    One of our Help Desk techs suggested I find out what size images ought to be for best use in PowerPoint and downscale the images being used to the recommended size. I am wondering if anyone out there knows what the best PPI is for a PowerPoint presentation. Also, what is the best pixel width and height for an image to cover the slide?

    Hope this is clear and someone knows what I'm talking about. <img src=/S/crossfingers.gif border=0 alt=crossfingers width=17 height=16>

    PowerPoint presentations that include large images do tend to get huge. But the real question is who your audience is going to be. If the plan is to use it with an LCD projector then they usually have an optimum size, and you might want to scale things close to that. Most are either 800x600 or 1024x768. Thus you would want to make the image a little smaller than that. On the other hand, if you intend to use it as a downloadable tool or distribute it on a CD, then you have to worry about people who run at 1600x1200 or 2560x1024 as well as those who run 640x480. Sorry this doesn't answer the question more clearly, but those are the issues. Just out of curiosity why are the images being change from GIF to JPG?

    You can really blow up file size by converting GIF's to JPG's without any increase in image quality. In fact sometimes you get weird patterns happening on the image.
