    ; 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.
