    // 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.
