How do I insert more than one background into a presentation?

Follow these steps in OpenOffice.org:

1. Select the slide where you need to change the background.
2. Select Format-Styles-Slide design...
3. Select the Load... button.
4. Select a category (of backgrounds)from the Load Slide Design popup. The Template list will update.
5. Select the new presentation under Templates.
6. Click OK in the Load Slide Design popup.
7. Click OK in the Slide design popup.

Depending on which templates are loaded into the distribution that you are using, not all of the categories of background templates may be available. Repeat above steps for all the individual slides in your file.

NOTE:  These instructions will only work if you have downloaded Presentation templates from the Samples and Templates section or have created your own templates.
