DataGridView ใส่รูปจากฐานข้อมูลแบบ file path แปลงข้อมูลยังไงครับ

 Dim str As String
        Dim da As OleDbDataAdapter
        Dim ds As New DataSet

        str = String.Format("SELECT item_id,item_name,item_picpath FROM tb_item ORDER BY item_id ")

        Try
            If isfind = True Then
                ds.Tables("item").Clear()
            End If
        Catch
        End Try


        da = New OleDbDataAdapter(str, con)
        da.Fill(ds, "item")
        If ds.Tables("item").Rows.Count >= 0 Then
            isfind = True


            With DataGridView1
                .ReadOnly = True
                .DataSource = ds.Tables("item")
            End With
