How to display information from the admin panel on the page of the WordPress site?

Question

Frontend

Hello, I need help. I use a plugin that creates iframe in this case, a site rotator. But, the picture is displayed only in the console, and I need to display it on the site page, what would be for all users. How can this be implemented? It may be possible to display using shortcodes, but then what function should be pulled up? Please help me figure it out.
