以下有两种方法，一种是直接链接别的网站，第二种是使用后台自带的功能。
方法一：
1. 打开文件 source\module\prelink.php
搜索get_webthumb 找到以下代码
function get_webthumb($web_pic) {
global $options;
if (!empty($web_pic)) {
$strurl = $options['site_root'].$options['upload_dir'].'/'.$web_pic;
} else {
$strurl = $options['site_root'].'public/images/nopic.gif';
}
return $strurl;
}
修改成以下代码
function get_webthumb($web_pic,$web_url) {
global $options;
if (!empty($web_pic)) {
$strurl = $options['site_root'].$options['upload_dir'].'/'.$web_pic;
} else {
$strurl= 'http://www.aizhan.com/ajaxAction/webthumb.php?domain='.$web_url;
}
return $strurl;
}
2.打开文件 source\module\website.php
搜索get_webthumb
找到
$web['web_pic'] = get_webthumb($web['web_pic']); 需要替换两次
全部替换成
$row['web_pic'] = get_webthumb($row['web_pic'],$row['web_url']);
3.打开文件 module\siteinfo.php
搜索get_webthumb
找到
$web['web_pic'] = get_webthumb($web['web_pic']); 这行
替换成
$web['web_pic'] = get_webthumb($web['web_pic'],$web['web_url']);
4.打开文件 module\linkinfo.php
搜索get_webthumb
找到
$link['web_pic'] = get_webthumb($link['web_pic']);
这行
替换成
$link['web_pic'] = get_webthumb($link['web_pic'],$link['web_url']);
方法二：修复官方的失效自带下载缩略图功能
修改 \source\include\function.php
搜索 save_to_local 函数
大约在434行
$imgurl = 'http://open.thumbshots.org/image.pxf?url='.$weburl;
替换成
$imgurl = 'http://www.myip.cn/webthumb.php?q='.$weburl;
保存即可，然后去后台-站点管理-下载图片
下载所有图片即可大约每个图片100K 图片保存在\uploads\website目录下
方法一：把网页图片调用其他网站的缩略图。这种方法比较节省服务器资源。具体操作如下。
1.打开文件 source\module\prelink.php
查找代码：

利用myip的接口显示缩略图图片是调用myip的不会占用自己服务器空间资源速度也有保证
myip是很老的站了相信不会轻易关闭
