Images and equations on a slide can overlap each other. In this case you can arrange how they are stacked by sending them backward or forward.

To do that:        

  1. Select an object (image or equation) on a slide
  2. On the ribbon, click the Bring to Front or Send to Back buttons.

    or

    Right-click an image or an equation and choose one of the four available actions from the drop-down menu:

  • Bring to Front
  • Send to Back
  • Bring Forward
  • Send Backward

You can select multiple objects on a slide and change arrangement of all selected objects at once.
