title: How to create url preview in JavaScript?
body: <p>Can someone help me with creation of a url previews in JavaScript? </p>
  
  <p>What I mean is this: Say I have a link on my site, I want the user to be able to mouse over the link, and have an image pop up that shows what the target of the link looks like.</p>
  
  <p>Don't worry about the css, I got that working, I just need the actual script to show the image.</p>
  
  <p>Currently I am doing it by showing up an iframe that actually renders the page, but this is not scalable and looks ugly. </p>
  
  <p>Having the page display premade images is not an option, since the links will be linking to dynamically generated user content. </p>
