Hello,

The images are not included with the demo import because of copyright issues that’s why they are not added.

If you want to add a promo pop up you need to create an HTML Block from Dashboard >> HTML Blocks.

Then you need to use the shortcode of the HTML block inside the promo popup text under Theme Settings >> Shop >> Promo Popup.
