Issue
The arrows end up on the bottom. Ive tried using margin to move them up but no luck. What can I add to the code so the arrows are on opposite sides? I used w3 for the code but on their example the arrows are on opposite sides. How can I go about doing that?
/* Slide Show */
var slideIndex = 1;
showDivs(slideIndex);
function plusDivs(n) {
showDivs(slideIndex += n);
}
function showDivs(n) {
var i;
var x = document.getElementsByClassName("mySlides");
if (n >= x.length) {slideIndex = 1}
if (n < 1) {slideIndex = x.length}
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
x[slideIndex-1].style.display = "block";
}
.mySlides {display:none;}

Solution
You only missed to link your stylesheet 'index.css'. I just put back the link to w3.css, fixed the missing buttonleft class, and changed the width of each image back to 100% it worked.
If you want to put some margin or resize the images you need to edit the element (div) that contains them.
Probably you need to edit the classes w3_content and/or w3-display-container.
/* Slide Show */
var slideIndex = 1;
showDivs(slideIndex);
function plusDivs(n) {
showDivs(slideIndex += n);
}
function showDivs(n) {
var i;
var x = document.getElementsByClassName("mySlides");
if (n >= x.length) {slideIndex = 1}
if (n < 1) {slideIndex = x.length}
for (i = 0; i < x.length; i++) {
x[i].style.display = "none";
}
x[slideIndex-1].style.display = "block";
}
.mySlides {display:none;}

But if you want to work with slides/carousel I highly recommend to see bootstrap carousel or tiny-slider, because they make your work easier and the result is pretty and responsive, but there are many more other plugins/tools to work with.
