PictureBox from file to BLOB to SQL Server database, then from DB to PictureBox
===

I have 1 Windows Form with 1 pictureBox, 1 textBox, and 3 buttons: LoadFromFile, SaveToDB,  and LoadFromDB.

using LINQ to SQL connection in App.config and next code in the Form:

    private void btnLoadFromFile_Click(object sender, EventArgs e)
    {
    // open file dialog
    OpenFileDialog open = new OpenFileDialog();
    // image filters
    open.Filter = "Image Files(*.jpg; *.jpeg; *.gif; *.bmp; *.png)|*.jpg; *.jpeg; *.gif; *.bmp; *.png";
    if (open.ShowDialog() == DialogResult.OK)
    {
    // display image in picture box
    picBox.Image = new Bitmap(open.FileName);
    // image file path
    textBox1.Text = open.FileName;
    }
    }

I could load Picture and its path to form.

now I need to save the picture to an image type field named [BLOBData] in my table: tblBLOB (BLOBID, BLOBData), so please what is the code to convert the picture to image type, and what is the code to convert then the image type to the picture to display it in the PictureBox control.
