<!DOCTYPE html>
<html>
  <head>
    <meta charset="utf-8">

  </head>
  <body>
    <a href="https://www.google.com" target="_blank">
      <img onmouseover="setInterval(mouseOver,500)" onmouseout="mouseOut()" id="a" src="1.jpg" style="height: 45vh; width: 23vw;">
    </a>
    <script>
      function mouseOver()
      {
        element=document.getElementById("a")
        if (element.src.match("pic_bulboff.jpg"))
        {
          document.getElementById("a").src="8.jpg";
        }
        else if (element.src.match("8.jpg"))
        {
          document.getElementById("a").src="6.jpg";
        }

You need to kill the Interval:

var Int;

function start(){
   Int=setInterval(yourfunc,1000);
}

function stop(){
   if(Int){
      clearInterval(Int);
      Int=null;
   }
}

You should clear the interval to stop the rotation. To approach this, I propose so call an external function (Lat's call onMouseOver).

When user enter, you save the intervalId in another variable. In this way, when mouse out you can call clearInterval.

      function onMouseOver() {
        interval = setInterval(mouseOver,500)

      {
        element=document.getElementById("a")
        if (element.src.match("pic_bulboff.jpg"))
        {
          document.getElementById("a").src="8.jpg";
        }
        else if (element.src.match("8.jpg"))
        {
          document.getElementById("a").src="6.jpg";
        }
        else
        {
          document.getElementById("a").src="1.jpg";

You can clearInterval the setInterval() onMouseOut.

Do something like this.

<!DOCTYPE html>
<html>

<head>
  <meta charset="utf-8">
  <title>Untitled Document</title>
</head>

<body>
  <a href="https://www.google.com" target="_blank">
    <img onmouseover="mouseEntered()" onmouseout="mouseOut()" id="a" src="1.jpg" style="height: 45vh; width: 23vw;">
  </a>
  <script>
    var interval;

    function mouseEntered() {
      interval = setInterval(mouseOver, 500)
    }

    function mouseOver() {
      element = document.getElementById("a")
      if (element.src.match("pic_bulboff.jpg")) {
        document.getElementById("a").src = "8.jpg";
      } else if (element.src.match("8.jpg")) {
        document.getElementById("a").src = "6.jpg";
      } else {
        document.getElementById("a").src = "1.jpg";
      }
    }

    function mouseOut() {
      document.getElementById("a").src = "1.jpg";
      if(interval)
       clearInterval(interval)
    }
  </script>
</body>

You need to stop the setInterval by using clearInterval. clearInterval cancel the setInterval by using the id returned by the setInterval.

Read more about clearInterval here.

https://developer.mozilla.org/en-US/docs/Web/API/WindowTimers/clearInterval

You can do it using.

<!DOCTYPE html>
<html>

<head>
  <meta charset="utf-8">
  <title>Untitled Document</title>
</head>

<body>
  <a href="https://www.google.com" target="_blank">
    <img onmouseover="mouseOver()" onmouseout="mouseOut()" id="a" src="1.jpg" style="height: 45vh; width: 23vw;">
  </a>
  <script>
    var timer;

    function change() {

      element = document.getElementById("a")
      if (element.src.match("pic_bulboff.jpg")) {
        document.getElementById("a").src = "8.jpg";
      } else if (element.src.match("8.jpg")) {
        document.getElementById("a").src = "6.jpg";
      } else {
        document.getElementById("a").src = "1.jpg";
      }

    }

    function mouseOver() {
      timer = setInterval(change, 500)
    }

    function mouseOut() {
      clearInterval(timer);
      document.getElementById("a").src = "1.jpg";
    }
  </script>
</body>

You have to use clearInterval function to clear the setInterval event. Here is an example.

<!DOCTYPE html>
<html>

<head>
    <meta charset="utf-8">
    <title>Untitled Document</title>
</head>

<body>
    <a href="https://www.google.com" target="_blank">
        <img onmouseover="setIntervalFunction()" onmouseout="mouseOut()" id="a" src="1.jpg" style="height: 45vh; width: 23vw;">
    </a>
    <script>
        var intervalVar = null;
        function setIntervalFunction() {
            intervalVar = setInterval(mouseOver,500);            
        }
        function mouseOver() {
            element = document.getElementById("a")
            if (element.src.match("pic_bulboff.jpg")) {
                document.getElementById("a").src = "8.jpg";
            } else if (element.src.match("8.jpg")) {
                document.getElementById("a").src = "6.jpg";
            } else {
                document.getElementById("a").src = "1.jpg";
            }
        }

        function mouseOut() {
            document.getElementById("a").src = "1.jpg";
            clearInterval(intervalVar);
        }
    </script>
</body>

You must use setTimeout to call function only once, because setInterval will repeat calls every n milliseconds. Also first make instant call and than call setTimeout to do it once more after some time.

<!DOCTYPE html>

  <meta charset="utf-8">

  <a href="https://www.google.com" target="_blank">
    <img onmouseover="mouseOver(); setTimeout(mouseOver, 500)" onmouseout="mouseOut()" id="a" src="http://downloadicons.net/sites/default/files/yellow-number-1-icon-24487.png" style="height: 200px; width: 200px;">
  </a>
  <script>
    function mouseOver() {
      element = document.getElementById("a")
      if (element.src.match("http://downloadicons.net/sites/default/files/yellow-number-1-icon-24487.png")) {
        document.getElementById("a").src = "http://www.drodd.com/images15/2-9.png";
      } else if (element.src.match("http://www.drodd.com/images15/2-9.png")) {
        document.getElementById("a").src = "http://pngimg.com/upload/small/number3_PNG14976.png";
      } else {
        document.getElementById("a").src = "http://downloadicons.net/sites/default/files/yellow-number-1-icon-24487.png";
      }
    }

    function mouseOut() {

You just can use CSSS-animation with keyframes. Look at snippet. Try to move mouse over an image

.test {
    margin: 30px;
    width: 200px;
    height: 150px;
    background: url("http://lorempixel.com/output/nature-q-c-200-150-1.jpg");
}
@keyframes BG-CHANGE {
    
    0% {
     background: url("http://lorempixel.com/output/nature-q-c-200-150-1.jpg");
    }
    30% {
      background: url("http://lorempixel.com/output/nature-q-c-200-150-7.jpg");
    }
    60% {
      background: url("http://lorempixel.com/output/nature-q-c-200-150-10.jpg");
    }
    100% {
     background: url("http://lorempixel.com/output/nature-q-c-200-150-1.jpg");
    }
}
.test:hover {
     animation: BG-CHANGE 6s infinite;
}

<div class="test"></div>

Use clearInterval and track the initial interval:

<!DOCTYPE html>
<html>

<head>
  <meta charset="utf-8">
  <title>Untitled Document</title>
</head>

<body>
  <a href="https://www.google.com" target="_blank">
    <img onmouseover="init()" onmouseout="mouseOut()" id="a" src="http://placecage.com/400/400" style="height: 45vh; width: 23vw;">
  </a>
  <script>
    var interval;

    function init() {
      interval = setInterval(mouseOver, 500)
    }

    function mouseOver() {
      element = document.getElementById("a")
      if (element.src.match("400/400")) {
        document.getElementById("a").src = "http://placecage.com/300/300";
      } else if (element.src.match("300/300")) {
        document.getElementById("a").src = "http://placecage.com/200/200";
      } else {
        document.getElementById("a").src = "http://placecage.com/500/500";
      }
    }

    function mouseOut() {
      document.getElementById("a").src = "http://placecage.com/400/400";
      clearInterval(interval)
    }
  </script>
</body>
