How to display a notification with image? - Libnotify

Hi all, this is the code:

#include <libnotify/notify.h>
#include <stdio.h>
#include <unistd.h>

int main()
{
    NotifyNotification *n;

    notify_init("Basics");

    n = notify_notification_new ("Summary",
                                 "\nThis is the message that we want to display",
                                  NULL, NULL);
    notify_notification_set_timeout (n, 5000); // 5 seconds

    if (!notify_notification_show (n, NULL))
    {
        return 1;
    }

    g_object_unref(G_OBJECT(n));

    return 0;
}

It displays a message without any problem, but I want to add a specific image to it as many apps do so...
Is this possible with libnotify? And if it is, how do I do it? :eek::confused:
