But you don't have to write anything into a file just to serve it. As you have learned, you can make a controller action that delivers a png, possibly based on parameters. So all you need is - have a controller & template that contains <img src="/path/to/my/action/serve_image?some=parameter"/> - the controllar action "serve_image" returns the image When the browser reads the first, it will query the second. There is nothing in between. That's HTTP/HTML 101.
