Answer 1

As simple as that, this will output the image with correct headers,
remember that you have to set the header() before flushing anything out of the output buffer
=> no echo or print before

$file = '../../somedirectory/image.jpg‘;
header('Content-Type:image/jpeg‘);
header('Content-Length: '.filesize($file));
echo file_get_contents($file);
