I started a new architecture website and I need a plugin to insert banners between posts on the front page. I can’t share the link with you here, but you can find it on my profile page so you can make an idea of how the website looks like. I’ve been looking for hours now, but I cannot find anything, the only thing I could see are plugins that work with widgets, but I don’t need them on the sidebar.
I am not sure about the plugin, but you can do it with a custom code. It’s important to investigate your theme structure at first, to find default wp loop. You can check following video, it might help.
