If any of the following causes an error and display_errors == 1, you'll get
output and  PHP will default to text/html:

header('Content-type :image/jpeg');
header('Content-Length: ' . filesize( $image ) );
$file = file_get_contents( $image );

If you have any whitespace prior to header(), you'll get output and PHP will
default to text/html.

You can avoid whitespace by never using an ending ?> tag.
