所以我曾经能够做到，但忘记了如何，因为我不得不重新开始，它的一部分

Dim bFile() As Byte = System.IO.File.ReadAllBytes(bmp)

这就是问题所在，我只需要上传 test.image 甚至 bmp（我保存的位图）或以某种方式从文件流上传图像，因为我不想保存到计算机磁盘...

        Dim clsRequest As System.Net.FtpWebRequest = _
DirectCast(System.Net.WebRequest.Create("ftp://ftp.myURL.info"), System.Net.FtpWebRequest)
        clsRequest.Credentials = New System.Net.NetworkCredential("myusername", "mypassword")
        clsRequest.Method = System.Net.WebRequestMethods.Ftp.UploadFile
        ' read in file...         
        Dim bFile() As Byte = System.IO.File.ReadAllBytes(bmp)
        ' upload file...         
        Dim clsStream As System.IO.Stream = _
        clsRequest.GetRequestStream()
        clsStream.Write(bFile, 0, bFile.Length)
        clsStream.Close()
        clsStream.Dispose()

谢谢

试试这个：
插入图像： 

Picturebox1.Image = New System.Drawing.Bitmap(New IO.MemoryStream(New System.Net.WebClient().DownloadData(UrlTOimg)))


上传图片： 

Using ms As New System.IO.MemoryStream
    PictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Png)
    Using wc As New System.Net.WebClient
        wc.UploadData("ftp://foo.com/bar/mumble.png", ms.ToArray())
    End Using
End Using

ftp地址+密码：

ftp://username:password@ftp.website.com/htdocs/ImageName.png

享受 =)
