Stop from loading Carousell on small devices -320px

I like this Carousel, but it does not work very good on small devices. How can I stop Carousel from loading on devices smaller than 320px. I have a @media on screen set to 320px. I tried adding the following but it did not work:
.jp-carousel-slide img {
display:none;
}
