Why I cannot save my picture in my DataBase?

Hi!

I wrote this codes to download my pictures. Its works well. Then each time I want I would like to save pictures in my database.
But sound that my saving's codes are wrong and there is a red line on this line:

pictureBox1.Image = dRow.ItemArray.GetValue(3);

I have this message: "Cannot implicitly convert type 'System.Drawing.Image'". An explicit
conversion exists (are you missing a cast?)

Can I have some help...

private void NavigateRecords()
        {
            DataRow dRow = ds1.Tables["Avi"].Rows[inc];
            txtBx_Name.Text = dRow.ItemArray.GetValue(1).ToString();
            txtBx_Birthday.Text = dRow.ItemArray.GetValue(2).ToString();
            pictureBox1.Image = dRow.ItemArray.GetValue(3);
        }



private void btnSave_Click(object sender, EventArgs e)
        {
            DataRow dRow = ds1.Tables["Avi"].NewRow();

            dRow[1] = txtBx_Name.Text;
            dRow[2] = txtBx_Birthday.Text;
            dRow[3] = pictureBox1.Image;

            ds1.Tables["Avi"].Rows.Add(dRow);

            UpdateDB();

            MaxRows = MaxRows + 1;
            inc = MaxRows - 1;

            btnAdd.Enabled = true;
            btnSave.Enabled = false;          

            
        }

private void btnDownload_Click(object sender, EventArgs e)
        {
            string Chosen_File = "";

            openFileDialog1.InitialDirectory = "C:";
            openFileDialog1.Title = "Insert an Image";
            openFileDialog1.FileName = "";
            openFileDialog1.Filter = "JPEG Images|*.jpg|GIF Images|*.gif";

            if (openFileDialog1.ShowDialog() == DialogResult.Cancel)
            {
                MessageBox.Show("Operation Cancelled");
            }
            else
            {
                Chosen_File = openFileDialog1.FileName;
                pictureBox1.Image = Image.FromFile(Chosen_File);
            }
