或许你没注意到，首页的菜单上面增加了美女欣赏，观赏地址：主要使用了php来读取JSon，然后判断，如果有图片，那么进行输出，如果没有图片，就直接返回，后面还使用了timthumb.php来截取图片。要使用本功能，你先要在进行注册，获取美女图片的API。
第一步：获取API内容，并且创建文件是否存在的判断函数
第二步：判断文件是否存在，如果文件存在那么显示
newslist as $key) {?>
picUrl);if ($exists) {?>
" target="_blank" rel="nofollow">;?>/meinv/timthumb.php?src=<?php echo $key->picUrl;?>&h=196&w=263&zc=1) title;?>
其中使用到了timthumb.php，里面的代码如下：
/*
- --- TimThumb CONFIGURATION ---
- To edit the configs it is best to create a file called timthumb-config.php
- and define variables you want to customize in there. It will automatically be
- loaded by timthumb. This will save you having to re-edit these variables
- everytime you download a new version
*/
