Hi there,
so for example – you would use a Page Hero element, as the image needs to be in your post content.
I would:
1. Don’t add the Page Hero to those pages.
2. Add a Featured image to the News Starter post.
3. Disable it so it won’t be displayed:

NOTE: 2 & 3 is only required if you want to have a featured image for display in your archives or for social sharing.
4. Now in the Post Content, add a GenerateBlocks Image block at the top of the post for displaying your image. You can then set the Image Block to Float Left, set its size in the sidebar settings and add some margin to get that design.
