It's easy to display a graphic file, such as a company logo, on every slide in a presentation. Simply add the graphic file to the Slide Master, and PowerPoint will display that graphic on every slide. (To access the Slide Master, choose Master from the View menu and then select Slide Master.)
Most likely, you'll end up with at least one slide where the graphic isn't appropriate. Now, you might consider deleting the graphic from the Slide Master and inserting it into each slide where you do want to display it, but that's not necessary. It's much easier to exclude the graphic from one or even a few slides. To exclude a graphic from a slide, do the following:
- Right-click the thumbnail slide in the Slide tab.
- Choose Background.
- In the resulting dialog box, check the Omit Background Graphics From Master option.
- Click Apply. Don't click Apply To All because that will remove the graphic from every slide. (That option doesn't even make sense to me in this spot.)
In PowerPoint 2007, do the following:
- In Normal view, click the appropriate slide in the Slides tab.
- Click the Design tab.
- Deselect the Hide Background Graphics check box in the Background group.
This does seem to be an all or nothing solution. If you add more than one graphic file to the Slide Master, you hide them all.
