Answer 1

图片上传到放图片的文件夹，数据库中只用放图片相对路径。
一般图片无组件上传用

传值的表单用文件类型。

Answer 2

图片有2个途径啊，一个是把图片变成2进制数存入数据库，另一种是无组件图片上传组件。网上都有做好的代码打包下载的，搜索asp无组件上传就有了

Answer 3

使用adodb.stream对象可以
举例
rs("file").appendchunk=objstream.read(objstream.size)
整体写出来代码太多 只给个思路 具体怎么用去 百度查吧

Answer 4

asp上传一般都用无组件上传，如果空间支持组件上传更好

图片一般上传到服务器文件夹目录，数据库记录图片路径即可
