I'm creating an program that needs to delete/overwrite an image called "Image.jpeg"
i have to code to upload already, but i need to be able to overwrite image.jpeg, so i was thinking of: delete file, upload new version
or: overwrite file
the problem is that i can't find anywhere how to achieve this
heres my code:

Try
            Using ms As New System.IO.MemoryStream
                PictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg)
                Using wc As New System.Net.WebClient
                    wc.UploadData _
                    ("ftp://username:password@domain.com/public_html/IMG/IMAGES/image.jpeg", ms.ToArray)
                End Using
            End Using
        Catch er As Exception
            MessageBox.Show(er.ToString)
        End Try
