Expected behavior

When an image part with Content-Description field is archived, e.g.:

Content-type: image/jpeg; name="image.jpg"
Content-Description: This is a JPEG file
Content-Disposition: inline; filename="image.jpg"
Content-transfer-encoding: base64

XXXX

Output should contain the description, i.e.:

• For the inline image (Content-Disposition: inline):

  <p>This is a JPEG file</p>
  <p><a href="..." ><img src="..." alt="JPEG image"></a></p>

• For the attachment (Content-Disposition: attachment, or non-images):

  <p><strong>Attachment:
  <a href="..." ><tt>image.jpg</tt></a></strong><br>
  <em>Description:</em> This is a JPEG file</p>

Actual behavior

With inline image, Content-Description is omitted.

• For the inline image (Content-Disposition: inline):

  <p><a href="..." ><img src="..." alt="JPEG image"></a></p>
