discuz X3空间主题列表 图片展现模式，discuz实现个人空间主题列表调用图片模式，discuz home图片列表
如果需要实现该呈现方式，我们需要首先了解discuz封面图片存储原理：
discuz没有将主题列表封面路径存在数据表中，只是在pre_forum_thread表中存了一个cover标识。然后用getthreadcover 函数调取，diy调用的图片也会产生缩略图，可以设置缩略图的质量。
封面图片存储路径格式：data/attachment/forum/threadcover/43/ec/81.jpg
getthreadcover 函数：
function getthreadcover($tid, $cover = 0, $getfilename = 0) {
global $_G;
if(empty($tid)) {
return '';
}
$coverpath = '';
$covername = 'threadcover/'.substr(md5($tid), 0, 2).'/'.substr(md5($tid), 2, 2).'/'.$tid.'.jpg';
if($getfilename) {
return $covername;
}
if($cover) {
$coverpath = ($cover < 0 ? $_G['setting']['ftp']['attachurl'] : $_G['setting']['attachurl']).'forum/'.$covername;
}
return $coverpath;
}
文件路径：/source/function/function_forum.php
实现方法：
修改：/source/language/home/lang_template.php
添加like 喜欢或查看
修改：/template/default/home/space_thread.htm
处理封面图：
{eval
$covername = 'threadcover/'.substr(md5($thread[tid]), 0, 2).'/'.substr(md5($thread[tid]), 2, 2).'/'.$thread[tid].'.jpg';
$coverpath = ($cover < 0 ? $_G['setting']['ftp']['attachurl'] : $_G['setting']['attachurl']).'forum/'.$covername;
}
