I am currently retrieving the path of the image, how can I retrieve the image itself?

I'm using asp.net so there is no picturebox.

protected void lnk_OnClick(object sender, EventArgs e)
    {
        int AdvertisementID = Convert.ToInt32((sender as LinkButton).CommandArgument);
        if (sqlCon.State == ConnectionState.Closed)
            sqlCon.Open();
        SqlDataAdapter sqlDa = new SqlDataAdapter("ViewByID", sqlCon);
        sqlDa.SelectCommand.CommandType = CommandType.StoredProcedure;
        sqlDa.SelectCommand.Parameters.AddWithValue("@AdvertisementID", AdvertisementID);
        DataTable dtbl = new DataTable();
        sqlDa.Fill(dtbl);
        sqlCon.Close();
        hfContactID.Value = AdvertisementID.ToString();
        AdsTb.Text = dtbl.Rows[0]["AdvertisementID"].ToString();
        itemTb.Text = dtbl.Rows[0]["Item"].ToString();
        ImageTb.Text = dtbl.Rows[0]["ImgPath"].ToString();
        ButSave.Text = "Update";
        btnDelete.Enabled = true;
    }

All you need to do is add an image control to your aspx page using markup like below.

<asp:Image id="Image1" runat="server"  AlternateText="Image text"  ImageAlign="left" />

Then, in your code-behind which you have provided in your post, you simply set the image url for above image control as shown in code below. (look at the line of code just after the comment saying //set image url of image control to display the image).

NOTE: I am assuming that dtbl.Rows[0]["ImgPath"].ToString() contains the file name of image as well as the full/relative virtual path to the image file. For example, if the image file is located under Images folder from the current page location then the relative path would be Images/imagename.jpg or you can give the full virtual path from root like ~/Images/imagename.jpg.

protected void lnk_OnClick(object sender, EventArgs e)
    {
        int AdvertisementID = Convert.ToInt32((sender as LinkButton).CommandArgument);
        if (sqlCon.State == ConnectionState.Closed)
            sqlCon.Open();
        SqlDataAdapter sqlDa = new SqlDataAdapter("ViewByID", sqlCon);
        sqlDa.SelectCommand.CommandType = CommandType.StoredProcedure;
        sqlDa.SelectCommand.Parameters.AddWithValue("@AdvertisementID", AdvertisementID);
        DataTable dtbl = new DataTable();
        sqlDa.Fill(dtbl);
        sqlCon.Close();
        hfContactID.Value = AdvertisementID.ToString();
        AdsTb.Text = dtbl.Rows[0]["AdvertisementID"].ToString();
        itemTb.Text = dtbl.Rows[0]["Item"].ToString();
        ImageTb.Text = dtbl.Rows[0]["ImgPath"].ToString();
        //set image url of image control to display the image
        Image1.ImageUrl =  ImageTb.Text;
        ButSave.Text = "Update";
        btnDelete.Enabled = true;
    }
