But some people here don't seem to recognise the different methods
even where both are available in their mailer. For example, both these
post structures have been sent to this list using Apple Mail (2.3445.8.2).
The first one produces "invisible" images that a text-only reader will
know nothing about; the second is satisfactory for readers, but the
poster might have been forced to eschew HTML to achieve this.
