In the Extras palette of the Slide Show dialog box, you can add clip art to slides. You can individually add as many graphics as you want, but using excessive graphics will affect performance (because of the increased file size).
Drag the clip art onto the slide.
Double-click the clip art.
Right-click and select Add To Select Slide(s) from the Context menu.
To resize a graphic, drag a corner of the bounding box.
To move a graphic, click the center of the clip art and drag it to a new location.
To change the stacking order of clip art, click a graphic and then choose an option from the Edit > Arrange menu.
