This pretty much is not a LISTSERV issue (though subscribers will most likely need to support MIME attachments, have enough mailbox space to support graphic files, have enough bandwidth via their ISP, as well as to not treat the message as a virus/spam). SET listname MIME would probably be the only LISTSERV list subscriber option, which may already be the default. Also, LANGUAGE= HTML DEFAULT-OPTIONS= MIME Specifying NOHTML will prevent the inline graphic and instead it will be a "clickable" attachment. /Pete
