Cannot upload Image to a SharePoint List

I'm working with a Visual WebPart and I want to upload a image from my FileUpload control to a SharePoint list. This is the code I'm using but I can't get it to work, (Title, prodnum, color, etc is working, but not image). I've also installed SparQube.

This is my ListView: .

protected void Button_Save_Click(object sender, EventArgs e)
{
    SPSite currentSite = SPContext.Current.Site;
    SPList myList = currentSite.RootWeb.Lists.TryGetList("SharePointDatabase");

    try
    {
        if (myList != null && FileUpload_Pic.PostedFile != null && FileUpload_Pic.HasFile)
        {
            SPListItem listItem = myList.Items.Add();

            listItem["Title"] = TextBox_Name.Text;
            listItem["ProductNumber"] = TextBox_ProdNum.Text;
            listItem["Color"] = TextBox_Color.Text;
            listItem["ListPrice"] = TextBox_ListPrice.Text;
            listItem["MoreInformation"] = TextBox_MoreInfo.Text;

            string fileName = Path.GetFileName(FileUpload_Pic.PostedFile.FileName);
            listItem["Image"] = fileName;

            listItem.Update();                                            

            TextBox_Search.Text = string.Empty;
            TextBox_Name.Text = string.Empty;
            TextBox_MoreInfo.Text = string.Empty;
            TextBox_ProdNum.Text = string.Empty;
            TextBox_Color.Text = string.Empty;
            TextBox_ListPrice.Text = string.Empty;

            Label_Exception.Text = "Saved to Database list.";

            Dispose();
        }
    }
    catch (Exception x)
    {
        Label_Exception.Text = x.Message;
    }

}
