2. <!--{if $attach[description]}--><p>{$attach[description]}</p><!--{/if}-->
3. <!--{if !$attach[price] || $attach[payed]}-->
4. <p>
5. <!--{if $thumbstatus && $attach[thumb]}-->
6. <!--{if $attachrefcheck || $hideurl}-->

替换为：

接下继续查找：

2. <!--{if $thumbstatus && $attach[thumb]}-->
3. <!--{if $attachrefcheck || $hideurl}-->
4. <a href="javascript:;"><img onclick="zoom(this, attachment.php?aid=$attach[aid]&k=$k&t=$timestamp&noupdate=yes&nothumb=yes&sid=$sidauth)" src="attachment.php?aid=$attach[aid]&k=$k&t=$timestamp&sid=$sidauth" border="0" id="aimg_$attach[aid]" onmouseover="showMenu(this.id, false, 2)" /></a>

第二步：打开templates/header.htm文件。 查找：

2. <script type="text/javascript" src="include/js/common.js?{VERHASH}"></script>

复制代码

在下面加：

3. <script>
4. function errpic(thepic){
5. thepic.src="images/nopic.gif"
6. }
7. </script>

复制代码

第三步：打开include/discuzcode.func.php文件。 查找：

1. "bbcodeurl(\\\\1, <img src=\\"%s\\" onload=\\"thumbImg(this)\\" alt=\\"\\" />)",

复制代码

替换为

2. "bbcodeurl(\\\\1, <img src=\\"%s\\" onload=\\"thumbImg(this)\\" alt=\\"\\" onerror=\\"javascript:errpic(this)\\"/>)",

复制代码

第四步：把图片传到images目录common文件夹，后台更新缓存。结束
