放到e目录下

修改第16行
$r=$empire->fetch1("select dianhua,chuanzhen,dianziyouxiang from phome_ecms_zhaopin where");
$r=$empire->fetch1("select 你要图片化的字段名 from 你要调用的数据表名 where");

然后模板添加
<img src="[!--news.url--]e/key/zhaopin.php?key=dianziyouxiang&id=[!--id--]" /></img>
<img src="[!--news.url--]e/key/zhaopin.php?key=你要图片化的字段名&id=[!--id--]" /></img>

可以复制PHP文件改名来达到多个数据库的调用
