So your problem, if I understand correctly, is that you need to attach an integer to a combo box item. This is pretty easy:

private class MyComboBoxItem
{
    public readonly string Text;
    public readonly int Value

    public MyComboBoxItem(string text, int value)
    {
        this.Text = text;
        this.Value = value;
    }

    public override string ToString()
    {
        return this.Text;
    }
}

// Code to add the "France" item to the combo box
MyComboBoxItem france = new MyComboBoxItem("France", 5);
myComboBox.Items.Add(france);

// The event handler that handles selection changed event.
void myComboBox_SelectedValueChanged(object sender, EventArgs e)
{
    MyComboBoxItem selectedItem = (MyComboBoxItem)myComboBox.SelectedItem;
    int value = selectedItem.Value;
}

You can use ComboBox.Text for the text to display and its ComboBox.SelectedValue.

In binding, you can use DispalyMember for text display and ValueMember for the corresponding value.

There are so many ways...are you planning on storing the images in a database? Search SQL images on this site, it should point you in the right direction.

My mistake, I didn't see the asp.net part of your original request. Guess I expected a question dealing with asp.net would be posted to the ASP.NET forum

Change the type of the combobox to a dropdownlist. You will find it in the properties.
