** after (default '
') - the html to output after the link
** between (default ' ') - the html to output between the link/image

** show_images (default true) - whether to show images (if defined).
** orderby (default 'id') - the order to output the links. E.g. 'id', 'name',

** You can also specify 'rand' as the order which will return links in a

** 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
** echo (default true) - whether to echo the results, or return them instead
