Since you don't mention the version of outlook, I'll assume you are using
outlook 2003 and mean ones that are attached to the message, since 2003
blocks external downloads by default and many porn messages have the image
attached.
The best method is disabling html content - it's east to enable per message
in 2003 but if this is not acceptable or you use other versions of outlook,
enabling junk mail or getting a good antispam program is your next option.
if you use an older version of outlook, a good antispam program is probably
the best, since it can't block external contect.
