I forgot to add a side-note to my post about the unique random number function. If the array count
is more than half of the random number max, the function could take a very long time to process,
maybe even go into an infinite loop. The best way to avoid this is to set the max at twice the
array count; i.e. if you want an array of 10 unique random numbers, the maximum random number needs
to be at least 20. For my purposes, I have 50 pictures to choose from, and the function randomly
picks 20 of them to display on the webpage, without displaying an image twice.
