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
此升级修改方法，在v5.7，v5.7sp1 测试通过，其他版本未测试，原理基本相同，请大家自行测试是否可行。
首先给 栏目表(`#@__arctype`)增加一个字段typeimg
alter table `#@__arctype` add `typeimg` varchar(200) not null default ;
修改catalog_add.php文件
打开dede/catalog_add.php
查找$querytemplate = “insert into `#@__arctype`
将
(reid,topid,sortrank,typename,typedir,
替换为：
(reid,topid,sortrank,typename,typedir,typeimg,
将
(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,
替换为：
(‘~reid~’,'~topid~’,'~rank~’,'~typename~’,'~typedir~’,'~typeimg~’,
查找$in_query = “insert into `#@__arctype`
将
(reid,topid,sortrank,typename,typedir,
替换为：
(reid,topid,sortrank,typename,typedir,typeimg,
将
(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,
替换为：
(‘$reid’,'$topid’,'$sortrank’,'$typename’,'$typedir’,'$typeimg’,
保存catalog_add.php
下面修改catalog_edit.php文件
打开dede/catalog_edit.php
查找$upquery = “update `#@__arctype` set
在 typedir=’$typedir’, 其下面增加一行：
`typeimg`=’$typeimg’,
保存catalog_edit.php

至此已经修改完成!
栏目图片的添加或修改图片时在 (栏目管理>高级选项)里面就会自动出现栏目图片添加的选择，点击选择图片，弹出窗口内选择浏览上传就ok
注意：前台栏目标签调用的时候，还需要改一个文件，才能实现栏目图片显示，否则只能通过sql语句才能显示图片。
打开：include/taglib/channel.lib.php
找到
if($type=='top')
{
$sql = select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
from `#@__arctype` where reid=0 and ishidden<>1 order by sortrank asc limit 0,$row;

替换成下面的：
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;

from `#@__arctype` where reid='$reid' and ishidden<>1 order by sortrank asc limit 0,$row;
}
调用方法：
<img src=”[field:typeimg /]” />
最近有很多网友问到修改的方法，现在我把已经修改好的后台文件分享出来，下载下来直接覆盖到后台就可以了。http://115.com/file/anqwqyi0
如果想同时在文章内容页调用栏目图片打开，修改includearc.archives.class.php
查找
if($this->channelunit->channelinfos['issystem']!=-1)
将
$query = “select arc.*,tp.reid,tp.typedir,ch.addtable
from `#@__archives` arc
left join #@__arctype tp on tp.id=arc.typeid
left join #@__channeltype as ch on arc.channel = ch.id
where arc.id=’$aid’ “;
$this->fields = $this->dsql->getone($query);
替换为：
$query = “select arc.*,tp.reid,tp.typedir,tp.typeimg,ch.addtable
from `#@__archives` arc
left join #@__arctype tp on tp.id=arc.typeid
left join #@__channeltype as ch on arc.channel = ch.id
where arc.id=’$aid’ “;
$this->fields = $this->dsql->getone($query);
