aspjpeg组件安装了,无显示水印
aspjpeg组件安装到了服务器上,代码也写好了，但是就不显示水印,有是有就在图片会显示三个小方格,不知道是啥原因,求解中
代码如下：
VBScript code

<%
set upload=new upload_file
if upload.form("act")="uploadfile" then
    filepath=trim(upload.form("filepath"))
    filelx=trim(upload.form("filelx"))
    
    i=0
    for each formName in upload.File
        set file=upload.File(formName)
 
 fileExt=lcase(file.FileExt)    '得到的文件扩展名不含有.
         '这里为开始判断只能加哪种类型的图片，这里限死了只能加gif,jpg,png,bmp
 fileExt=lcase(fileExt)
 if fileExt <> "gif" and fileExt <> "jpg" and  fileExt <>"png" and  fileExt <>"swf" then    
 Response.Write("<span style=""font-family: 宋体; font-size: 9pt"">您只能上传 [gif/jpg/png/swf] 类型的文件！　[ <a href=# onclick=history.go(-1)>重新上传</a> ]</span>")
Response.End()
end if'判断结束
