Another feature when working with Prezi images is the superimposition. When we import an image into the presentation, the image will be at the top level or layer. If we want to superimpose our images, to show one over the other, we have to use the right-click options and look for the options Bring to Front or Send to Back. In this way, we tell Prezi where we want our images to reside in the presentation.
It is good to know that the presentation topics behave like images, too, meaning that we can superimpose an image in front of a topic or vice-versa.
