Read what I wrote again. You'll have two actions in your controller. One, this
download action you've shown us, does nothing other than send the PNG to the
browser. The second one will show a normal CakePHP ctp view file, and in that
view, you'll create an img tag, just as you would to display any other static
image, except that its src (I think I wrote href before but I meant src) will
point not to a static file on disk but to the URL of your download action (i.e.
"$this->link(array('action' => 'download', ...))").
Try getting the download action working first, so that when you call it up in
the browser, it displays the image by itself. If it's not working, maybe read
about media views, which handle a lot of this header business for you.
