Fix missing images issue #81

[jma26]

What does this PR do?

After thoroughly looking into the reverted code. There was a minor annoyance in how Github pages reads nested folders, images through the current directory and requires us to put a period, "./" before the slash. This fixed the disappearing images when live.

Additional changes in addition to the images

• Minor bug with the randomized numbers generated from 1-16 (numbers between the 1st image and 16th image). Had to add a +1 so it would randomly select between 1-16 instead of 0-15.
• Minor update disabling the image from being clicked with pointer-events set to none instead of using the attribute "disable" on it like a button before
