For me it worked a code like this in the action:
$response = $this->getResponse() ;
$response->setContentType('the contet type header');
$response->setContent($image->asString());
$response->send() ;
But this supposes that you have the image as an object that supports the
asString() method, whick returns the data as string instead of outputing
them directly.
One php method that returns string data is file_get_contents('filepath') but
it reads from disk. Maybe you could find something that returns a memory
image as string. Try setContent($image) as a speculation. If you find the
solution say it here.
