See if this guide helps.

On this post is a simple way to add a ranking based on post count.

User ranking system?

Where it says
echo '<div class="all-stars"><i class="svg-icon one-star"></i></div>'

That is where you can add your images like this.

echo '<div class="all-stars"><img src="image source"/></div>'

Make sure they are different for each post count specified in the snippet.

You may need different CSS than what was mentioned in the post though.
