on the place.img page, I can't put in 400 by 400 and I cannot get the images to change every time I click on refresh
On placeimg.com The height and width boxes won't let me change the size, so I just put 400 x 400 in my code and it pulled up the correct image; however, it won't change the image every time I refresh like it did in the tutorial.

Once you fetch an image, your browser caches it and then gives you the same one back when you reference the same URL instead of fetching a new one.
document.querySelector("img").src += "?nocache=" + Math.random();
Note that this particular script only targets the first image on the page.
