外链图片及附件图片失效自动用指定图片代替，不至于显示的是一个X，适用discuz!x2及discuz!x1.5

【注】修改前，请将原文件做好备份工作，需要备份的文件有 emplatedefault orumdiscuzcode.htm文件、templatesdefaultcommonheader.htm文件、source unction unction_discuzcode.php文件

如果你的论坛使用的是其他风格模板，修改对应风格模板里面的对应文件即可

第一步：打开 emplatedefault orumdiscuzcode.htm
查找

复制代码

在所有关于附件的img标签中添加一个 onerror="javascript:errpic(this)"属性，共四处，作用是对于附件图片失效自动用指定图片代替================================================================
第二步：打开templates\default\common\header.htm文件。
查找：

<script type="text/javascript" src="{$_G[setting][jspath]}forum.js?{VERHASH}"></script>

复制代码

在下面加：

<script>
function errpic(thepic){
thepic.src="./static/image/common/nopic.gif"
}
</script>

复制代码

这里指定图片为static/image/common/nopic.gif，你也可以根据自己的需要进行修改！
================================================================

第三步：打开source\function\function_discuzcode.php文件。
查找：

"bbcodeurl('\\1', '<img $attrsrc="{url}" onload="thumbImg(this)" alt="" />')"

复制代码

替换为

"bbcodeurl('\\1', '<img $attrsrc="{url}" onload="thumbImg(this)" alt="" onerror="javascript:errpic(this)"/>')"

复制代码

就是在上面的代码的中img标签中加添加一个 onerror="javascript:errpic(this)"属性，作用是对于外链图片失效自动用指定图片代替
到这里修改就结束了！附图片失效自动用指定图片代替 for 7.0，地址：http://www.discuz.net/thread-1280572-1-1.html
==========================================================================

discuz x1.5修改基本一样，不过由于和x2在代码上略有不同，这里只稍加说下，第二、三步完全相同第一步打开\template\default\forum\discuzcode.htm
查找

function attachinpost($attach) {
global $_G;
$attach['refcheck'] = (!$attach['remote'] && $_G['setting']['attachrefcheck']) || ($attach['remote'] && ($_G['setting']['ftp']['hideurl'] || ($attach['isimage'] && $_G['setting']['attachimgpost'] && strtolower(substr($_G['setting']['ftp']['attachurl'], 0, 3)) == 'ftp')));
$aidencode = aidencode($attach['aid']);
$GLOBALS['aimgs'][$attach['pid']][] = $attach['aid'];
$widthcode = attachwidth($attach['width']);
$is_archive = $_G['forum_thread']['is_archived'] ? '&fid='.$_G['fid'].'&archiveid='.$_G[forum_thread][archiveid] : '';
}
<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} style="cursor:pointer" onclick="zoom(this, '{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes¬humb=yes{else}{$attach[url]}$attach[attachment]{/if}')" src="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode{else}{$attach[url]}$attach[attachment]{/if}" border="0" id="aimg_$attach[aid]" onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})" alt="$attach[imgalt]" title="$attach[imgalt]" />

替换成
