** before (default '') - the html to output before the link
** after (default '<br />') - the html to output after the link
** between (default ' ') - the html to output between the link/image
** and it's description. Not used if no image or show_images == true
** show_images (default true) - whether to show images (if defined).
** orderby (default 'id') - the order to output the links. E.g. 'id', 'name',
** 'url', 'description' or 'rating'. Or maybe owner. If you start the
** name with an underscore the order will be reversed.
** You can also specify 'rand' as the order which will return links in a
** random order.
** show_description (default true) - whether to show the description if
** show_images=false/not defined
** show_rating (default false) - show rating stars/chars
** limit (default -1) - Limit to X entries. If not specified, all entries
** are shown.
** show_updated (default 0) - whether to show last updated timestamp
