JOIN

I am trying to output news.  An article can have an image or not sometimes.
Can someone help me get this to work in Postgres?

 select a.article_id, a.title, a.url, a.synopsis, a.publish_date,
 c.parent_category_id, c.category_id, c.category_name,
 i.server_image_name
 from ((article a JOIN article_category_assoc acs ON a.article_id =
acs.article_id)
 JOIN category c ON c.category_id = acs.category_id)
 LEFT OUTER JOIN (image i JOIN article_image_assoc aia ON i.image_id =
aia.image_id)
 ON a.article_id = aia.article_id
 where i.image_type_id = 1
 and a.live_date <=  #CreateODBCDate(Now())#
 and a.active_ind = TRUE
 and a.status_id = 2
 and c.category_id=#intCategoryID#

Thanks
