title: How do I replace a certain image on a website with another image?
body: <p>There's this site that has an image I want to replace. Just like the scripts that replace the background of a page, like Google. </p>
  
  <p>In the html, it's in <code>img scr</code>. How do I replace that specific source on the page with another source so every time I visit that page, it displays the image I want instead of the one that's normally there?</p>
