That was the program that BookerC1/Angie found for us in the original first post of this thread and she has great instructions too!
One feature I use a lot is the flip function, I even have been flipping several banners in the queue and then having members resubmit. So often it's the right side that contains the best feature and focus and with the ATP banner pushing the left side over a bit, that right side gets cut off so it makes a better banner when flipped.
