try using gtk_timeout_add instead of a while loop, the while loop is probably
avoiding the gtk_main loop to happen... something like:

int dto;

[...]
void testrgb_rgb_test (GtkWidget *drawing_area){
   printf("pImColor=%d\n",pImColor);
   printf("bufIm=%d\n",bufIm);
        
   /* calls testrgb_rgb_cb every 100 miliseconds) */
   dto = gtk_timeout_add (100, testrgb_rgb_cb (drawing_area);
 
}

int testrgb_rgb_cb (gpointer data)
{
     GtkWidget *drawing_area = (GtkWidget*) data;

     SiguienteFrame();    /*read images from the FG*/
 
       gdk_draw_gray_image (drawing_area->window,
          drawing_area->style->white_gc,
          0, 0, WIDTH+10, HEIGHT+10, GDK_RGB_DITHER_NONE,
          bufIm, WIDTH);

        return TRUE; /* tells gtk_timeout that he should continue calling me */
}
