A function as an image to a 12 plot figure.

Hi, I have an assignment that is about making a norwegian flag, using codes, and put it up as a function. I have reach the state where i need to make a 12 plot figure using the function, which basically is an image. How can I do that? I will leave the matlab file used to get the flag, just so any helper can provide me with some help to what i need to do to make 12 plot figure of the made image.
