Images uploaded with netlify cms doesn't display on the blog site

Hi,

when Im trying to add new post to my blog and include image then the image never appears
Here's an example - created a post titled "welcome"
`https://myblog.com/blog/welcome/`

In the netlify cms I can see the image being displayed in the preview window when creating the post. After I save it and open post on my blog image cannot be displayed. Here's the path to the image taken from my blog:
`https://myblog.com/blog/welcome/assets/blog.jpeg`

In the file structure, the image itself is saved under:
`static/assets/blog.jpeg`

page itself is saved under:
`content/blog/welcome.md`

Here's my config.yml
`
> backend:
> name: github
> repo: myusername/reponame
>
> media_folder: static/assets
> public_folder: assets
>
> collections:
> name: blog
> label: Blog
> folder: content/blog
> create: true
> fields:
> - { name: path, label: Path }
> - { name: date, label: Date, widget: date }
> - { name: title, label: Title }
> - { name: description, label: Description }
> - { name: body, label: Body, widget: markdown }
`

To resolve this issue I have tried with different images and also to edit gatsby-config.js - thought that editing line below from content to static would help but didn't change much:

> {
> resolve: `gatsby-source-filesystem`,
> options: {
> path: `${__dirname}/content/assets`,
> name: `assets`,
> },
> },

It's fresh out of the box installation, is it a bug or Im missing some essential steps in the config?

Also, when creating a post Im asked to provide a path - what's that for?

Thanks for Your effort to help me make it work!
