此功能添加涉及到以下文件：
dede/catalog_add.php
dede/catalog_edit.php
dede/templets/catalog_add.htm
dede/templets/catalog_edit.htm
include/taglib/channel.lib.php
此升級修改方法，在v5.7，v5.7sp1 測試通過，其他版本未測試，原理基本相同，請大家自行測試是否可行。
首先給 欄目表(`#@__arctype`)增加一個字段typeimg
alter table `#@__arctype` add `typeimg` varchar(200) not null default ;
修改catalog_add.php文件
打開dede/catalog_add.php
查找$querytemplate = “insert into `#@__arctype`
將
(reid,topid,sortrank,typename,typedir,
替換為：
(reid,topid,sortrank,typename,typedir,typeimg,
將
(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,
替換為：
(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,'~typeimg~’,
查找$in_query = “insert into `#@__arctype`
將
(reid,topid,sortrank,typename,typedir,
替換為：
(reid,topid,sortrank,typename,typedir,typeimg,
將
(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,
替換為：
(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,'$typeimg’,
保存catalog_add.php
下面修改catalog_edit.php文件
打開dede/catalog_edit.php
查找$upquery = “update `#@__arctype` set
在 typedir=’$typedir’, 其下面增加一行：
`typeimg`=’$typeimg’,
保存catalog_edit.php

至此已經(jīng)修改完成!
欄目圖片的添加或修改圖片時在 (欄目管理>高級選項)里面就會自動出現(xiàn)欄目圖片添加的選擇，點(diǎn)擊選擇圖片，彈出窗口內(nèi)選擇瀏覽上傳就ok
注意：前臺欄目標(biāo)簽調(diào)用的時候，還需要改一個文件，才能實(shí)現(xiàn)欄目圖片顯示，否則只能通過sql語句才能顯示圖片。
打開：include/taglib/channel.lib.php
找到
if($type=='top')
{
$sql = select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description

}
替換成下面的：
if($type=='top')
{
$sql = select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
from `#@__arctype` where reid=0 and ishidden<>1 order by sortrank asc limit 0,$row;

//if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid'];
if($typeid==0) {
return '';
}
$sql = select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
from `#@__arctype` where reid='$typeid' and ishidden<>1 order by sortrank asc limit 0,$row;
}
else if($type==self)
{
if($reid==0) {
return '';
}
$sql = select id,typename,typeimg,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
from `#@__arctype` where reid='$reid' and ishidden<>1 order by sortrank asc limit 0,$row;
}
調(diào)用方法：
<img src=”[field:typeimg /]” />
最近有很多網(wǎng)友問到修改的方法，現(xiàn)在我把已經(jīng)修改好的后臺文件分享出來，下載下來直接覆蓋到后臺就可以了。http://115.com/file/anqwqyi0
如果想同時在文章內(nèi)容頁調(diào)用欄目圖片打開，修改includearc.archives.class.php
查找
if($this->channelunit->channelinfos['issystem']!=-1)
將
$query = “select arc.*,tp.reid,tp.typedir,ch.addtable
from `#@__archives` arc
left join #@__arctype tp on tp.id=arc.typeid
left join #@__channeltype as ch on arc.channel = ch.id
where arc.id=’$aid’ “;
$this->fields = $this->dsql->getone($query);
替換為：
$query = “select arc.*,tp.reid,tp.typedir,tp.typeimg,ch.addtable
from `#@__archives` arc
left join #@__arctype tp on tp.id=arc.typeid
left join #@__channeltype as ch on arc.channel = ch.id
