How Do I Layer Images in PowerPoint?
In PowerPoint 2013, each time you add a new object, it appears in a new layer above the other objects.This isn't something you notice when objects are side by side, but if you want one shape, text box or other object to appear above or below another, layers become quite important. Using the options under the Drawing Tools Format tab, you can move an object or a group of objects to any layer you choose.
Open a PowerPoint file and go to any slide that contains multiple objects, or add some objects. Click any object that you want to appear in a layer below all other objects. Note that a Format tab is highlighted beneath the Drawing Tools tab, whether you have selected a drawing, a photo, text box or any other object.
Click the Drawing Tool's "Format" tab while your object is selected. The Bring Forward and Send Backward options appear in the Arrangement group. Click the small "Arrow" beside Send Backward and select "Send to Back." The object is moved to the bottom layer so that all other objects are above it.
Select an object that you want to bring towards the top. Click "Bring Forward" under the Format tab. This moves the object one level higher. Click "Bring Forward" again to bring it another layer higher or click the "Arrow" and select "Bring to Front."
Using Groups and Layers
Drag the cursor over two or more objects. Click the Drawing Tools "Format" tab. In the Arrange group, beside the Bring Forward and Send Backward options are three small icons. The middle icon, resembling two superimposed squares, is the Group icon. Click the "Arrow" beside the Group icon and select "Group." The objects are now linked together as if they were one object.
Drag the grouped objects to any location on the slide. Click the "Format" tab again and change their layer position by selecting "Bring Forward" or "Send Backward."
Ungroup the objects when you are satisfied with their position by clicking the "Arrow" beside the Group icon again and selecting "Ungroup."
