This is a place to tell people about your show, what drew you to podcasting, or what you hope to accomplish. It’s also a Page, which we tend to use for more permanent content. Pages can be primarily text-based, or you can upload images of yourself and your experiences to help you tell your story.
The photo above is the Featured Image for this Page; you’ll see where to edit it on the Edit Page. You can choose any image you like for this space — as long as you have the rights to use it! — or you can choose to have no image at all.
A website like Unsplash is a good place to go to find interesting images that you can use freely on your own website. This one is by Jacob Hodgson. Make sure you give credit when you do make use of someone else’s work.
