Yes, the magic string is definitely: return $this->renderText('/myimage/url.jpg');
or return $this->renderText($imagecontent); The use of that line will make Symfony forget about rendering any template, just like " return sfView::NONE; " would, but that the latter flushes any output as well. If you want to put something in a template, like outputting a file on disk, the template would look like this: <?php readfile($path_to_file_on_disk); ?> Cheers!
