For the Main Stage of Story Map's side panel layout, how do you create an interactive tab to group 2 or more .png images together without adding a map? Is there such a function?
Could you clarify which Story Map app template you are using? How about just making one image that contains both of your images? There's not a way to provide access to two different images in the main stage, unless there's a third party web control like a little gallery control that you can set up on the web, and then embed as web content into your story map.
