Image duplication for sphinx docs required

# Issue
## Problem Description
Right now, the images in the readme.md have to also be in the docs folder for the paths to be solved correctly when generating the docs with sphinx.

## Expected Behavior
One copy of the images should be fine.

## What Needs to be Done
Find some way to make sphinx search the repo root not only the docs folder. or alternative find mutually compatible path where to store the images.

## How Can It Be Tested or Reproduced
Look at readme on github and docs online or locally via `make html` in the docs folder.
