I am trying to show my blog posts as an excerpt with a photo – what you call blog large image. I cannot do that for my mine. All I have is an excerpt with no photo (https://raybulson.com/blog/). How do I change this?
Just create a new page with any name and set the page template to Blog Image Large under Page Attributes which you can find on right side of your page editor and set this page as your homepage and you will have Blog Image Large into your blog.
