首先，圖片在頁面中能查找選擇。設計表單頁面index.asp和上傳選擇頁upload.asp，upload.asp在index.asp中以iframe包含。

其次，所選圖片應能上傳到某文件夾。建立一文件夾uploadimg

最后，傳上去的圖片應如何引用？很顯然，采用UBB立即顯示。upload.asp的指向對象upfile.asp具有寫入UBB標簽的功能。

無組件上傳調試文件夾
    -- index.asp
    -- upload.asp
    -- upfile.asp
    -- uploadimg文件夾

圖片上傳采用稻香老農的無組件上傳。所以upload.inc文件必不可少。

1，upload.inc（拷貝以下文本框的所有代碼）

2，表單頁面index.asp。注意框架包含的上傳選擇頁upload.asp

3，上傳選擇頁upload.asp 注意： enctype="multipart/form-data"

4，最后一個文件 upfile.asp 主要作用：生成圖片名，并將圖片上傳，同樣也要將UBB標簽寫入index.asp中的textarea中。
（拷貝以下文本框的所有代碼）

當然，保持圖片的文件夾uploadimg不能少
