Image is not propagated from index.ipynb to README.md

I am trying to add an image to one of my Markdown cells, but I am lost at how to make it appear in README.md and the corresponding github-page.

I did run nbdev_build_docs, and it does pick up the latest text changes but for some reason leaves out the image.

Here is the cell I am having trouble with in index.ipynb

 {
   "cell_type": "markdown",
   "metadata": {},
   "source": [
    "# Simulation of the proton beam tracker/calorimeter\n",
    "\n",
    "> This project will have tools to aid a simulation and optimizatin of the proton beam tracker/calorimeter in application for determining the corrections to the proton stopping powers for treatment planning.\n",
    "![gate simulation](media/gate_simulation.png)\n"
   ]
  },

and here the what I get in README.md

# Simulation of the proton beam tracker/calorimeter
> This project will have tools to aid a simulation and optimizatin of the proton beam tracker/calorimeter in application for determining the corrections to the proton stopping powers for treatment planning.


As you see no images :cry:

I solved the problem by moving the image into the next cell. Not sure why it got stripped in the first cell.
