-If you'd like to change the disposition or add a custom file name, you can use the second and third paramaters. To use the default disposition (attachment), leave the second parameter blank. Here's an example::
-  
-	$this->email->attach('/path/to/photo1.jpg', 'inline');
-	$this->email->attach('/path/to/photo1.jpg', '', 'birthday.jpg');

+To use the default disposition (attachment), leave the second parameter blank,
+otherwise use a custom disposition::

+If you'd like to use a custom file name, you can use the third paramater::

+If you need to use a buffer string instead of a real - physical - file you can

+parameter as mime-type::
