Display of full Blog

I found the solution you gave here

However, is there a way to have the “Feature image” of the post to appear on that Blog page (Blog | Renardo Design) like on the home page (renardo.co.uk)?

I removed the fact the “Feature image” appears at the top of a post but I’d like it to appear in the post listing on the Blog page.

Is there any action to allow one and not the other?
