Andrew, I honestly haven't done extensive testing to notice if it flickers or not. I did set the timer to 1000ms to test that it would go grab the file and it didn't seem to flicker, but I am not 100% confident I have it all working smoothly. If you don't mind, keep posting to this thread with anything you discover and I'll do the same.
