//  There are two ways of embedding images in emails: with CIDs
//  and without.  When using CIDs, the IMG SRC attributes use
//  urls that begin with "CID:" and the corresponding image
//  embedded within the email includes a Content-ID header field.
//  When not using CIDs, the IMG SRC attribute can have a URL,
//  path, etc. and the corresponding image embedded within
//  the email has a matching Content-Location header field.

//  When testing with GMail, if CIDs are used the email will
//  be displayed with images blocked (by default) unless
//  the user allows them to be displayed.  Without CIDs,
//  the images are automatically displayed.

//  When testing with Eudora, Mozilla Thunderbird, and Outlook Express,
//  embedded images display correctly with our without CIDs.

//  When testing with Yahoo! Mail, embedded images display OK.
//  However, the Yahoo! Mail user has the option of blocking
//  images.  If this is turned on, the CID images will still
//  display correctly even though images are blocked.  Why?
//  It's because when viewing the email there is no external
//  HTTP request to fetch an image.  Therefore, a spammer
//  cannot get an indication that you've read the email.
//  However, if CIDs are not used, the images are blocked by
//  any Yahoo! Mail user that has image blocking turned on --
//  even though the images are embedded.

//  I haven't tested Hotmail yet...
//  Regardless, there is no perfect solution.  If CIDs are used,
//  GMail users may block your embedded images, if CIDs are not
//  used, Yahoo! Mail users may block your embedded images.

//  I recommend setting using CIDs.  This is what Mozilla Thunderbird
//  does by default, and it's the more clear an unambiguous way
//  to indicate that images are indeed embedded.
