title: Jekyll assets get deleted
body: <p>I'm using jekyll to build a simple static website. My _config file is basically the default.  I have an issue with including images in my website. </p>
  
  <p>I have an images directory inside my _site/assets directory (which I simply copy pasted into). Upon running the website with bundle (locally), the images folder gets deleted from the directory. If I copy it back there then the images are properly shown on the site, but upon refresh they are deleted again. </p>
  
  <p>As I understand it, I need to build the folder using bundle so it doesn't delete it, but the exact way this is done is unclear to me. Can someone please explain what is happening and how I could fix it?</p>
