Navigate to a slide you want to add this content to and then click the "Slide" drop-down arrow from the top menu. Here you will be able to choose between three options: Popup Images, Popup Video, and Slide Audio.

You can either upload an image or video from your device or browse in your current Image Libary for any images that you want to add.

Once you name the Image or Video, you will have a new "Popup Media" button on your slide. If you click that button, it will show the content that you decided to display.

To remove this Popup, navigate back into the "Popup Images" or "Popup Video" menu under the Slide drop-down. From there, you can either edit the image you have or completely remove it by hitting the "X".

Slide audio follows the same process as shown above. The menu is slightly different after clicking on the option in the "Slide" drop-down menu. There are a few options you can choose from when creating this popup.
