Hello dcharlot,
I think the right way to do that is to first create all your images, put them in an array an d then, when you start to acquire image from your amera, just replave one image after the other in the array using a shit register and the index.
Refer to the attached VI, I hope this will help you.
We have two ears and one mouth so that we can listen twice as much as we speak.
