前言说明

默认图片鼠标移动过去会显示图片名和下载，如果开启了图片列表还有设为封面，有些Discuz!站长需要让帖子内容页面更美观，可以使用以下办法去除。

修改方法

打开/template/default/forum/discuzcode.htm
找到

<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']}

有两处的下面，以下内容删除

onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"

保存后 后台更新缓存
如果想要去掉下载和保存相册，只保留设为封面：
打开template/default/forum/discuzcode.htm文件
修改第258行，源码如下：

<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} style="cursor:pointer" id="aimg_$attach[aid]" aid="$attach[aid]" src="{STATICURL}image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '{$_G[setting][showexif]}')" 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"{if $_GET['from'] != 'preview'} onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if} />

修改为：

<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} style="cursor:pointer" id="aimg_$attach[aid]" aid="$attach[aid]" src="{STATICURL}image/common/none.gif" onclick="zoom(this, this.getAttribute('zoomfile'), 0, 0, '{$_G[setting][showexif]}')" 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"{if $_GET['from'] != 'preview'} {if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if}{/if} />

找到第260行代码如下：

<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} id="aimg_$attach[aid]" aid="$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"{if $_GET['from'] != 'preview'} onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if} />

修改为：

<img{if $attach['price'] && $_G['forum_attachmentdown'] && $_G['uid'] != $attach['uid']} class="attprice"{/if} id="aimg_$attach[aid]" aid="$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"{if $_GET['from'] != 'preview'} {if $firstpost && $_G['fid'] && $_G['forum']['picstyle'] && ($_G['forum']['ismoderator'] || $_G['uid'] == $attach['uid'])}onmouseover="showMenu({'ctrlid':this.id,'pos':'12'})"{/if}{/if} />

删除267行代码，如下：

<a href="forum.php?mod=attachment{$is_archive}&aid=$aidencode¬humb=yes" target="_blank">{lang download}</a>

修改后，如果后台->版块->编辑->扩展设置，没有开启图片列表模式，则鼠标移动到图片上时不会有任何提示。
