CSS: images that are not displayed for jQuery datepicker

Question

I use datepicker from here: https://jqueryui.com/datepicker/

I clicked on the source code of the source, then copied the code.

Three lines below:

<link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
  <script src="//code.jquery.com/jquery-1.10.2.js"></script>
  <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>

I copied the / css scripts and saved them locally, then I downloaded the smoothness template, unzipped it, placed the images in / images on my server, but the arrow images do not appear, this is how it looks: http://postimg.org/image/bcnvipy61 /

Did I copy the images in the wrong place or something else? (I am not good at CSS)

EDIT (after reading the comments below:

<link rel="stylesheet" href="css/jquery-ui.css">
    <script src="js/jquery-1.10.2.js"></script>
    <script src="js/jquery-ui.js"></script>

therefore the ways:

css/
js/
images/
