you are blocking with your own loop before entering inside the gtk+ main
loop with the following call:

if you want to wait one second before drawing onto the window, use
g_timeout_add() and call gdk_draw_image() inside the callback passed to
that function.

please, read the documentation about the GLib main loop at:
