# See Global Unlock Sample for sample code.

# 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.

# 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.
