// This example requires the Chilkat API to have been previously unlocked.

// Set a top-level MIME header field.
$mime->SetHeaderField('Subject','Test HTML email with JPG image.');

// Generate a Content-ID.  This will contain random data that will allow
// the HTML's "img" tag to reference the image part in the MIME.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.Crypt2')
