Think of it this way Pete -- why waste bandwidth sending graphics to the
entire list and risk malware distribution when for a given topic perhaps
less than 10% would have interest in a particular thread. Best to post the
graphics to a web site where those interested can click on the link to
gather more details and visuals. This is the way its done on other list
services. Less risk, less bandwidth usage...
