So you can use wrap anything with {{^Image}}{{/Image}} so that only if the Image field is not empty it will be rendered. So use that and put in some <br> tags in between and you’ll be done.
I learned these through observing templates others share for specific decks, or the ones I find in shared decks section. I think observation is a good way of learning for us non-coders. You’ll find interesting things people do.
One more thing, you can also use {{#Image}} {{/Image}} which will render what’s in between only when Image is there. I think these will come in handy. Tell us if you need further help.
This will help you. I can’t get into details here, how everything works. But you should start reading into CSS and HTML. There are probably also easier ways with the “position” styling.
