title: Grails - Loading image from the controller
body: <p>I am trying to retrieve zip file from FTP, unzip it, and get xml file and image file from them and parse the xml, display the contents of xml and image. </p>
  
  <pre><code>byte[] image = ftpClientService.getThumbnailInZip(customer.ftpUser, 
      customer.ftpPassword, customer.ftpHost, customer.ftpToWrapDirectory, 
      fileName) 
  FileOutputStream fos1 = new FileOutputStream("zip.img") 
  try { 
      fos1.write(image); 
  } finally { 
      fos1.close(); 
  } 
  return [
      command: this, 
      fileName: fileName, 
      applicationName: applicationName, 
      contentProvider: contentProvider, 
      operatingSystem: operatingSystem, 
      handSets: handSets, 
      zipImg:"zip.img" ]
  </code></pre>
  
  <p>I could finish the xml part successfully and image also I am able to retrieve from the zip in a byte format( i could convert it to a file using file outputstream), </p>
  
  <p>Now I am stuck in sending the image to gsp and to display that. Any inputs are much appreciated.</p>
  
  <p>Thanks</p>
