Is there a way to have a Codeigniter controller return an image?

Question

I was wondering if there was a way for a controller to, instead of returning a string, or a view, return an image (be it JPG, PNG etc). For example, instead of ending with a $t

Answer 1

I would do a

$computedImage = 'path/to/the/image.ext';
$this->load->helper('file');
$this->output->set_content_type(get_mime_by_extension($computedImage))->set_output(file_get_contents($computedImage));

If this helps. Cheers!
