DZ（Discuz!）群组图标（变量：$group[icon]）默认会被压缩成48*48像素，如若拉伸放大就会变模糊，解决方法如下：
打开\source\function\目录下的function_forum.php
查找：$img->Thumb($upload->attach['target'], './'.$uploadtype.'/'.$upload->attach['attachment'], 48, 48, 'fixwr');
其中的48,48就是宽高了，改成你要的规格即可
例如：$img->Thumb($upload->attach['target'], './'.$uploadtype.'/'.$upload->attach['attachment'], 66, 66, 'fixwr');
注意：修改后，已上传的群组图标还是小的，需要重新上传才会变大变清晰。
