前台调用栏目时需要显示图标，整理一下：
第一步：“系统->SQL命令工具” ， 插入sql语句
alter table dede_arctype add imgtype varchar(<span style="color: #800080;">100</span>)
第二步：进入后台管理文件目录(默认为：dede目录)，找到”catelog_add.php“下的 228行,把下面的替换默认的（在SQL语句添加了”typeimg“）
<span style="color: #800080;">$in_query</span> = "<span style="color: #000000;">INSERT INTO `#@__arctype`(reid,topid,sortrank,typename,typedir,isdefault,defaultname,issend,channeltype,
tempindex,templist,temparticle,modname,namerule,namerule2,
ispart,corank,description,keywords,seotitle,moresite,siteurl,sitepath,ishidden,`cross`,`crossid`,`content`,`smalltypes`,`typeimg`)
VALUES('</span><span style="color: #800080;">$reid</span>','<span style="color: #800080;">$topid</span>','<span style="color: #800080;">$sortrank</span>','<span style="color: #800080;">$typename</span>','<span style="color: #800080;">$typedir</span>','<span style="color: #800080;">$isdefault</span>','<span style="color: #800080;">$defaultname</span>','<span style="color: #800080;">$issend</span>','<span style="color: #800080;">$channeltype</span><span style="color: #000000;">',

'</span><span style="color: #800080;">$ispart</span>','<span style="color: #800080;">$corank</span>','<span style="color: #800080;">$description</span>','<span style="color: #800080;">$keywords</span>','<span style="color: #800080;">$seotitle</span>','<span style="color: #800080;">$moresite</span>','<span style="color: #800080;">$siteurl</span>','<span style="color: #800080;">$sitepath</span>','<span style="color: #800080;">$ishidden</span>','<span style="color: #800080;">$cross</span>','<span style="color: #800080;">$crossid</span>','<span style="color: #800080;">$content</span>','<span style="color: #800080;">$smalltypes</span>','<span style="color: #800080;">$typeimg</span>')";
第三步：找到”catelog_edit.php“下的36行把下面的替换默认的（在SQL语句添加了”typeimg“）
<span style="color: #800080;">$upquery</span> = "<span style="color: #000000;">UPDATE `#@__arctype` SET
issend='</span><span style="color: #800080;">$issend</span><span style="color: #000000;">',

</span><span style="color: #800080;">$uptopsql</span><span style="color: #000000;">
WHERE id='</span><span style="color: #800080;">$id</span>' ";
第四步：进入后台管理文件目录(默认为：dede目录)/templets/ 下的 “catalog_add.htm 和 catalog_edit.htm" 文件，再加入下面代码：
<span style="color: #0000ff;"><span style="color: #800000;">script </span><span style="color: #ff0000;">language</span><span style="color: #0000ff;">='javascript' </span><span style="color: #ff0000;">src</span><span style="color: #0000ff;">="js/main.js"</span><span style="color: #0000ff;">></span><span style="color: #800000;">script</span><span style="color: #0000ff;">></span></span>
并在想放置的位置加入下面代码：
<span style="color: #0000ff;"><span style="color: #800000;">tr</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">td </span><span style="color: #ff0000;">colspan</span><span style="color: #0000ff;">="2"</span><span style="color: #0000ff;">></span>

<span style="color: #0000ff;"><span style="color: #800000;">tbody</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">tr</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">td </span><span style="color: #ff0000;">width</span><span style="color: #0000ff;">="90"</span><span style="color: #ff0000;"> class</span><span style="color: #0000ff;">="bline"</span><span style="color: #ff0000;"> height</span><span style="color: #0000ff;">="24"</span><span style="color: #0000ff;">></span><span style="color: #ff0000;"> </span>imgmm：<span style="color: #0000ff;"></span><span style="color: #800000;">td</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">td </span><span style="color: #ff0000;">class</span><span style="color: #0000ff;">="bline"</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">input </span><span style="color: #ff0000;">type</span><span style="color: #0000ff;">="text"</span><span style="color: #ff0000;"> name</span><span style="color: #0000ff;">="typeimg"</span><span style="color: #ff0000;"> id</span><span style="color: #0000ff;">="imgmm"</span><span style="color: #ff0000;"> style</span><span style="color: #0000ff;">="width:300px"</span><span style="color: #ff0000;"> class</span><span style="color: #0000ff;">="text"</span> <span style="color: #0000ff;">/></span>
<span style="color: #0000ff;"><span style="color: #800000;">input </span><span style="color: #ff0000;">name</span><span style="color: #0000ff;">="imgmm_bt"</span><span style="color: #ff0000;"> type</span><span style="color: #0000ff;">="button"</span><span style="color: #ff0000;"> class</span><span style="color: #0000ff;">="inputbut"</span><span style="color: #ff0000;"> value</span><span style="color: #0000ff;">="浏览..."</span><span style="color: #ff0000;"> onclick</span><span style="color: #0000ff;">="SelectImage('form1.imgmm','big')"</span> <span style="color: #0000ff;">/></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">td</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">tr</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">tbody</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">table</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"><span style="color: #800000;">input </span><span style="color: #ff0000;">type</span><span style="color: #0000ff;">="hidden"</span><span style="color: #ff0000;"> name</span><span style="color: #0000ff;">="dede_addonfields"</span><span style="color: #ff0000;"> value</span><span style="color: #0000ff;">="imgmm,img"</span> <span style="color: #0000ff;">/></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">td</span><span style="color: #0000ff;">></span>
<span style="color: #0000ff;"></span><span style="color: #800000;">tr</span><span style="color: #0000ff;">></span></span></span></span></span></span></span></span></span></span></span>
第五步：调用栏目通边 channel 标签调用，所以要更改， 进入/include/taglib/channel.lib.php文件，找到78行,把以下的代码替换默认（添加typeimg字段查询）
<span style="color: #0000ff;">if</span>(<span style="color: #800080;">$type</span>=='top'<span style="color: #000000;">)
{
</span><span style="color: #800080;">$sql</span> = "<span style="color: #000000;">SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,typeimg
From `#@__arctype` WHERE reid=0 And ishidden1 order by sortrank asc limit 0, </span><span style="color: #800080;">$line</span> "<span style="color: #000000;">;
}
</span><span style="color: #0000ff;">else</span> <span style="color: #0000ff;">if</span>(<span style="color: #800080;">$type</span>=='son'<span style="color: #000000;">)
{
</span><span style="color: #0000ff;">if</span>(<span style="color: #800080;">$typeid</span>==0) <span style="color: #0000ff;">return</span> ''<span style="color: #000000;">;
</span><span style="color: #800080;">$sql</span> = "<span style="color: #000000;">SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,content,typeimg
From `#@__arctype` WHERE reid='</span><span style="color: #800080;">$typeid</span>' And ishidden1 order by sortrank asc limit 0, <span style="color: #800080;">$line</span> "<span style="color: #000000;">;
}
</span><span style="color: #0000ff;">else</span> <span style="color: #0000ff;">if</span>(<span style="color: #800080;">$type</span>=='self'<span style="color: #000000;">)
{
</span><span style="color: #0000ff;">if</span>(<span style="color: #800080;">$reid</span>==0) <span style="color: #0000ff;">return</span> ''<span style="color: #000000;">;
</span><span style="color: #800080;">$sql</span> = "<span style="color: #000000;">SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,typeimg
FROM `#@__arctype` WHERE reid='</span><span style="color: #800080;">$reid</span>' And ishidden1 order by sortrank asc limit 0, <span style="color: #800080;">$line</span> "<span style="color: #000000;">;
}</span>
最后一步：就是在前台调用了
{dede:channel type='self' typeid='15' row='8' currentstyle="
