To create an action means that you are writing
a procedure of steps that is to be repeated each
time you press the play button.
To start off, look at the size of the images that
you will be working with. If your image size is
720x720 pixels, you can use a base of 1000x1000 pixels.
Always look at the biggest number here and make sure
that you go bigger. In this case my widest side is
4765 pixels. This is just your base!
