discuz手机版 图片缩略图大小设置/修改清晰度
emplatedefaultmobileforumdiscuzcode.htm和
emplatedefault ouchforumdiscuzcode.htm
找到discuzcode.htm文件，搜索“200”会有两处代码如下
function imagelist($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')));
$mobilethumburl = $attach['attachimg'] && $_G['setting']['showimages'] && (!$attach['price'] || $attach['payed']) && ($_G['group']['allowgetimage'] ||$_G['uid'] == $attach['uid']) ? getforumimg($attach['aid'], 0, 200, 200, 'fixnone') : '' ;
$aidencode = packaids($attach); $is_archive = $_G['forum_thread']['is_archived'] ?"&fid=".$_G['fid']."&archiveid=".$_G[forum_thread][archiveid] : ''; }
size参数改大了之后你再在手机上看效果，缩略图是不是变大了？
看看，是不是我的网站缩略图还是原来那么大（200PX），但是清晰度怎么异常高呢？还有个小窍门，暂且让我保留一会儿，呵呵~
找到 static/image/mobile/style.css
修改这段样式中的红色字体
.plc .pi .message img,.plc .pi .img_one img { margin:0px 4px 0px 0; max-300px; max-height:300px; }
