Can’t remove placeholders

This is the blog page which I have called “The Story”. It contains the Hello World post that I have called the journey in. I am using a theme called “Klopp”. I am learning to do most things one at a time but I cannot put an image in the placeholder next to what was “Hello World”
Help would be great.
