Hello! I’d like to create featured images on my blog posts and podcast pages.

On my blog page, the featured images from my previous website host carried over but they are duplicated in the actual posts. You can see them here: http://www.creativeandmoneywise.com/blog

On the podcast page, I see no way to add featured images to each post. http://www.creativeandmoneywise.com/podcast

Ideally, for the both the blog posts and podcast posts I’d like to choose whether or not I want a featured image.

Thanks!
