    //  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.
