discuz插件的事，我又跑到csdn来问，相信组织的力量！

这个插件呢，是仿贴吧的，在帖子列表显示缩略图，是我很喜欢的一种风格，适用于X3.0，但是为了客户端，我只能用X2.5版本，这个插件在X2.5不工作，无法生成缩略图我就是想改一改代码，让其在X2.5环境下工作，自用，不商用。
在X3.0下，是能生成一个存放缩略图的文件夹，里面存放有缩略图。但是在2.5下，没有发现这个文件夹，所以感觉在build这一步出了问题。
下面贴出thumbbuilder.class.php这个文件的代码，请高手分析一下，为什么没有在data/attachment/下生成tiebalist这个文件夹。

buildthumb.inc.php内的内容，好像也有用处呢

这个你找原插件作者去瞅瞅吧！
