注明：如果你安裝在不同的數據庫，需要在sql中指定數據庫，我這邊是jtb，與公司的織夢dedecms不是安裝在同庫中。 
調用圖文帖子的方法： 
{dede:sql sql="SELECT jtb.pre_forum_threadimage.tid, jtb.pre_forum_threadimage.attachment, jtb.pre_forum_thread.tid, jtb.pre_forum_thread.fid, jtb.pre_forum_thread.subject FROM jtb.pre_forum_threadimage 
LEFT JOIN jtb.pre_forum_thread ON jtb.pre_forum_thread.tid = jtb.pre_forum_threadimage.tid 
 WHERE displayorder >=0 LIMIT 0 , 2"} 
<li><a href="/bbs/forum.php?mod=viewthread&tid=[field:tid /]"><img src="bbs/data/attachment/forum/[field:attachment/]" width="153px" height="100px" /></a></li> 
<li><a href="/bbs/forum.php?mod=viewthread&tid=[field:tid /]">[field:subject function="cn_substr('@me',28)" /]</a></li>
