Attach is used to add objects such as files or documents to a message. You can add binary and image attachments of the same file to your message. Fax recipients receive only the image and local users get both attachments. Local users can view and print the image component of the message received whether or not they have the application in which the attachment was originally created.

You can add attachments to any message. They can be overlays, images, binary files or messages.
