// The MHT component can be used to convert an HTML page
// from a URL, file, or in-memory HTML into an email
// with embedded images and style sheets.
Chilkat.Mht mht = new Chilkat.Mht();

// Any string argument automatically begins the 30-day trial.

// 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.
