Can't save image to MYSQL-DB through vb.net application

[sashiksu]

I'm wondering how to save image to MYSQL-DB via vb.net application. At the last I find some way to save image. But 'some type of images' doesn't save in that way. By 'some type of images' I mean diffrent widths,heights and resolutions.
For example I use this code to save image. On database there are two columns in table.

Dim mstream As New System.IO.MemoryStream()
        propic.Image.Save(mstream, System.Drawing.Imaging.ImageFormat.Jpeg)
        Dim arrImage() As Byte = mstream.GetBuffer()
        mstream.Close()

        query = "INSERT INTO client(client_id, pro_pic) VALUES(@client_id, @pro_pic)"
        Dim cmd = New MySqlCommand(query, con)
        cmd.Parameters.AddWithValue("@client_id", (TextBox1.Text))
        cmd.Parameters.AddWithValue("@pro_pic", arrImage)
        Try
            con.Open()
            cmd.ExecuteNonQuery()
            MsgBox("Image Has Been Saved", "Save Picture")
        Catch ex As Exception
            MsgBox(ex.Message)
            Exit Sub
        End Try
        If (con.State = ConnectionState.Open) Then
            con.Close()
        End If

when I use diffrent sizes widths,heights or resolution size images this occure error.
The error say : "Data too long for column 'pro_pic' at row 1"

Now I want to know about why this shows and how to get rid this.....

I'm using MS-SQL rather than MYSQL. Perhaps this code snippet will give you some idea.
