Working with tracks is the key to superimposing different image layers So that you can insert more objects in front of a background, which each contain an animation.

So proceed in this way, if you create a picture-in-picture effect:

1.From the Toolbox drag a chapter object into the Timeline.

2.In the empty chapter object insert a picture.

3.Insert additional pictures by dragging these onto “drag here to create a new track". Each image which is to be displayed on top of another image, must be locate in the Timeline under the relevant (background) image.

Make sure that objects that are to be displayed on a background are set to Off in the Fill background properties.
