To add attachments to an email, you will need to use the MultiPartEmail class. This class works just like SimpleEmail except that it adds several overloaded attach() methods to add attachments to the email. You can add an unlimited number of attachments either inline or attached. The attachments will be MIME encoded.

The simplest way to add the attachments is by using the EmailAttachment class to reference your attachments.

In the following example, we will create an attachment for a picture. We will then attach the picture to the email and send it.
