title: How to I change the size of an image in Github/Markdown?
body: <p>I'm editing a Readme.md file in a Github repository and have inserted a picture (see <a href="https://github.com/khpeek/FMCW-radar" rel="noreferrer">https://github.com/khpeek/FMCW-radar</a>). The picture takes up the full width but is rather grainy that way, and I would prefer to make it smaller. Is there any way to do that?</p>
  
  <p>P.S. I've tried the commands on
  <a href="https://stackoverflow.com/questions/14675913/how-to-change-image-size-markdown">How to change image size Markdown?</a>, but they don't seem to work.</p>
