thank in advance

you can simple math like:

var img = document.queryselector('img');  img.addeventlistener('click', onclick, false);      function onclick() {      this.removeattribute('style');        var deg =math.floor(math.random() * 360);         //split degrees in 8 values       var cad = deg%8;//get closest value       deg = cad*45;//set      var css = '-webkit-transform: rotate(' + deg + 'deg);';        this.setattribute(          'style', css      );  }
img { transition: transform 1s linear; vertical-align: middle; }
<img src="http://elevatingpolitics.com/wp-content/uploads/2016/10/ep-wheel.png" alt="" usemap="#linkwheel" width="500" height="auto" style="">

note: may want put center in different picture or remove text , use div on picture
