This bug is present in horde-3.0.5

When viewing attached MS Word documents, images inside the documents are
extracted by wvhtml and created in the temporary directory (/tmp in my
case). Unfortunately, the html returned to the user does not contain any
directory instruction so that all images are shown as broken links.

A solution is to add a regular expression to
lib/Horde/MIME/Viewer/msword.php which rewrites to <img src > part.
Replacing 
return $data
by
return preg_replace('/<img width="(\d+)" height="(\d+)" alt="([^"]+)"
src="([^"]+)"/i', '<img width="${1}" height="${2}" alt="${3}"
src="/wvTmpImages/${4}"', $data);
instructs the browser to fetch to images from wvTmpImages

This directory can then be created as an alias in Apache 

Alias /wvTmpImages/ "/tmp/"

<Directory /tmp>
<Files *.png>
Order allow,deny
Allow from all
</Files>
Order allow,deny
Deny from all
</Directory>
