title: Using jquery ready() function but still not fast enough? Ideas?
body: <p>Small question that I hope someone can answer.  </p>
  
  <p>I'm creating this personal chrome extension to help me test out content manipulation on various sites.  On one of these sites, I am simply replacing an existing <code>&lt;img&gt;</code> with a different image and wrapping that jquery <code>replaceWith()</code> function in <code>$(document).ready()</code> function.  </p>
  
  <p>When navigating to the page, though, you can still see the original image for a split second before it swaps them.  </p>
  
  <p>Is there any way to arrest the loading page until the image swap completes?</p>
