Several of these things did not work for me... however, this did. Might help someone else in the future. Here is the CSS:
.img-area {
display: block;
padding: 0px 0 0 0px;
text-indent: 0;
width: 100%;
background-size: 100% 95%;
background-repeat: no-repeat;
background-image: url("https://yourimage.png");
}
