If the Word articles are Word documents then ensure the images are embedded
in the page - these documents display in Word (in the browser) when
downloaded. If the images are embedded, then ask in a forum or newsgroup
that deals specifically with Word.
If the articles are HTML pages constructed with Word (cut and paste, or
saved as HTML) then ensure the hidden pagename_files folder (thicket
folder) is also published. This should happen if you publish the entire
website (all pages or changed pages), but will not happen if you only
publish the single page or use another FTP program - some FTP clients will
not show hidden folders.
