title: RefineryCMS Image URL Incorrect
body: <p>I'm writing an engine for RefineryCMS for a product photo gallery. I'm writing the gallery page using backbone and doing most of the rendering via frontend templates and javascript using backbone. So basically I am just sending my products to the client as JSON and the client builds the page.</p>
  
  <p>Also the app is setup to save images to Amazon s3.</p>
  
  <p>Now each product can have many Photos related to it. When I send these photos down as JSON I determine the url of the image which is stored as a Refinery::Image by calling</p>
  
  <p>image.url()</p>
  
  <p>and send the url to the client. Then in the client side code I use the url as the src attribute of an image tag.</p>
  
  <p></p>
  
  <p>However the url I send down does not exist on my server. </p>
  
  <p>I'm not extremely familiar with image_fu and how it is goes about generating the server side images. If someone could help me figure out how to generate image urls that work that would be awesome.</p>
