Add a border to your first example and you will see where the image comes up short.
.jacketd {
width: 606px;
height: 344px;
cursor: pointer;
border:3px solid red; /*add this to see where image is*/
border-radius: 25px ;
background: url("https://i.imgur.com/AJDZEOX.jpg") no-repeat 0 0;
}
EDIT:
You could also add background-size:cover; to the ruleset above to stretch that image, it doesn’t distort it since it’s a blurry image to begin with.
