title: rails convert html to image
body: <p>I'm looking for a way to convert html tags to a image on the fly...</p>
  
  <p>That means, that I want to be able to make a image_tag with a path to a method which returns the image created form html.</p>
  
  <p>I was looking for a solution on that, but couldn't come up with a proper way to solve that... </p>
  
  <p>Any Ideas?</p>
