Answer 1

Your gsp:

Your controller:

def draw() {
  byte[] imageInBytes = imageService.getImageInBytes() //should return byte array 

  response.with{
    setHeader('Content-length', imageInBytes.length.toString())
    contentType = 'image/jpg' // or the appropriate image content type
    outputStream << imageInBytes
    outputStream.flush()
  }
}
