多图片上传到指定的目录并存到数据库
类别: ASP教程 
关于图片上传的例子在网上有很多文章和原代码。但是每次上论坛浏览帖子的时候都是看到很多网友对图片上传感到头疼和麻烦。其实这个问题也是曾经让我感到头疼。也看过了不少的文章和代码。现在我写的这篇文章是把我比较喜欢的一篇代码和动网里的高手对这篇代码优化后再加上我增加一些代码结合出来的！呵呵，其实这篇文章是沾了写这篇代码的人(稻香居士)和动网里那些高手的光。:)
好了，不说废话了。开始来搭建所需要的环境和数据结构！
先新建一个名字叫photo的文件夹。(我在这里就是把图片上传到这个文件夹里的。)建立一个名字叫database的数据库。再接着建立一个名字叫sFile的表。表里设计四个字段分别是id(int),image(varchar),image1(varchar),image2(varchar)。我这里用的数据库是SQL。
