X3的最新修改方法：
查找：
<p><strong>$attach[filename]</strong> <em class="xg1">($attach[attachsize], {lang downloads}: $attach[downloads])</em></p>
将其删除或者注释掉
查找：
<p class="xg1 y">$attach[dateline] {lang upload}</p>
将其删除或者注释掉（这里你还可以改成其他的样式，也会很好看）
X2.5/X3的方法（这个方法能保证删除这些信息之后还能人工设置封面）：
1.查找：
<div class="tip tip_4 AImg_tip" id="aimg_$attach[aid]_menu" style="position: absolute; display: none">
X3 20121101版本查找：
<div class="tip tip_4 aimg_tip" id="aimg_$attach[aid]_menu" style="position: absolute; display: none" disautofocus="true">
修改为：
<div {if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}class="tip tip_4 aimg_tip" id="aimg_$attach[aid]_menu" {/if}style="position: absolute; display: none">
2.查找：
<div class="tip_c xs0">
<div class="y">$attach[dateline] {lang upload}</div>
<a href="forum.php?mod=attachment{$is_archive}&aid=$aidencode¬humb=yes" title="$attach[filename] {lang downloads}:$attach[downloads]" target="_blank"><strong>{lang download}</strong> <span class="xs0">($attach[attachsize])</span></a>
<!--{if $attach[description]}--><br />$attach[description]<!--{/if}-->
<!--{if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}-->
删除中间几行，效果如下：
<div class="tip_c xs0">
<!--{if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}-->
3.查找：
<br /><a href="forum.php?mod=ajax&action=setthreadcover&aid=$attach[aid]&fid=$_G[fid]" onclick="showWindow('setcover{$attach[aid]}', this.href)">{lang set_cover}</a>
去掉：前面的
<br />
针对X2和X2.5的,删除：
onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"
1.查找：
<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} style="cursor:pointer" id="aimg_$attach[aid]" src="{STATICURL}image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'))" zoomfile="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes¬humb=yes{else}{$attach[url]}$attach[attachment]{/if}" file="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode{else}{$attach[url]}$attachthumb{/if}" inpost="1" alt="$attach[imgalt]" title="$attach[imgalt]" onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})" />
<!--{else}-->
改成：
<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} style="cursor:pointer" id="aimg_$attach[aid]" src="{STATICURL}image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'))" zoomfile="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes¬humb=yes{else}{$attach[url]}$attach[attachment]{/if}" file="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode{else}{$attach[url]}$attachthumb{/if}" inpost="1" alt="$attach[imgalt]" title="$attach[imgalt]" />
<!--{else}-->
2.查找：
<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} id="aimg_$attach[aid]" src="{STATICURL}image/common/none.gif" zoomfile="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes¬humb=yes{else}{$attach[url]}$attach[attachment]{/if}" file="{if $attach[refcheck]}forum.php?mod=attachment{$is_archive}&aid=$aidencode&noupdate=yes{else}{$attach[url]}$attach[attachment]{/if}" $widthcode id="aimg_$attach[aid]" inpost="1" alt="$attach[imgalt]" title="$attach[imgalt]" onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})" />
改成：
