title: Difference between "./images/pic.png" and "images/pic.png"?
body: <p>Hello I recently stumbled upon something that I think has to do with formality. I have always used this to refer to files like this:</p>
  
  <pre><code>&lt;img src="images/cute_cat.png" /&gt;
  </code></pre>
  
  <p>However I recently saw people using this instead:</p>
  
  <pre><code>&lt;img src="./images/cute_cat.png" /&gt;
  </code></pre>
  
  <p>My question is if there's any logical explanation or if it's just a formality thing that some like to use and some don't.</p>
