How to store and retrieve images in sql server database with vb.net using picturebox

Let's have a table containing images (instead of max you can use desired size):

CREATE TABLE dbo.STORED_IMAGES
     (
     ID int NOT NULL  IDENTITY (1, 1),
     Img varbinary(MAX) NULL
     ) 

Storing image:

Dim CMD As New SqlClient.SqlCommand("insert into STORED_IMAGES(Img) values(@Img)",cn)
CMD.Parameters.Add("@Img", SqlDbType.VarBinary, Integer.MaxValue).Value = ReadFile(Path)

Function for reading file:

Private Function ReadFile(sPath As String) As Byte()
        Dim data As Byte() = Nothing
        Dim fInfo As New IO.FileInfo(sPath)
        Dim numBytes As Long = fInfo.Length
        Using fStream As New IO.FileStream(sPath, IO.FileMode.Open, IO.FileAccess.Read)
            Dim br As New IO.BinaryReader(fStream)
            data = br.ReadBytes(CInt(numBytes))
        End Using
        Return data
    End Function

Getting file from DB:

Dim fcmd As New SqlCommand("select Img from STORED_IMAGES where ID=@ID", cn)
fcmd.Parameters.Add("@ID", SqlDbType.Int).Value = 3 'e.g.
Dim bytes As Byte() = fcmd.ExecuteScalar

I suppose that with tableadapters your datatable will contain column with type Byte().
