好了，少说多做，本示例在w2kServer,IIS5,SQL SERVER7中测试通过。
如有不明白的可到精华区查“图象”或“图片”关键字找到答案，或写信给我。
示例一共有三个文件：upload.htm(上传界面)
process.ASP(处理程序)
showimg.ASP(显示图象)
数据库:在pubs数据库中建立一个新表名为imgtest
字段名 类型 长度
-----------------------------------------------------
id int (自动编号)
img iamge(Access为OLE)
imginfo nchar 50
以下是三个文件的代码:
upload.htm
