Description

TLDR:
Edits _layouts/post.html to not show the image specified in the front matter in the post itself if page.image.post is false. Also added documentation for the image field in _posts/2019-08-08-write-a-new-post.md.

Changes Made:

_layouts/post.html on line 39

{% if page.image %} became {% if page.image and page.image.post != false %}

_posts/2019-08-08-write-a-new-post.md on line 98

Added the following:

## Image

To add an image to the post so that it shows on the preview, embeds, and beginning of the post itself, you can specify the `image` field in the _Front Matter_ as follows:

``​`yaml
---
image: 
  path: /path/to/image.jpeg
  alt: this is some alt text
---
``​`

You can also use the `post` subfield if you only want the image to show up in the preview and embeds, and *not* in the post.

``​`yaml
---
image: 
  path: /path/to/image.jpeg
  alt: this is some alt text
  post: false
---
`​``
