I am getting an ajax response from a PHP. I want to decode the response , and get the 3 URL’s

The code is HTML/JS

<script type="text/javascript">
 $(document).ready(function() {
$(".goButton").click(function() {
   var dir =  $(this).attr("id");

   var imId = $(".theImage").attr("id");
   $.ajax({
      url: "viewnew.php",
      data: {
         current_image: imId,
         direction    : dir
      },
      success: function(ret) {
          alert(ret);
         $(".theImage").attr("src", ret);


         if ('prev' == dir) {
            imId ++;
         } else {
            imId --;
         }
         $("#theImage").attr("id", imId);
      }
   });

});
});
</script>


<body>
<img id="416" class="theImage" src="" />
  <a href="#null" class="goButton" id="next">Next</a>
</body>

And the PHP file is 

$query = 'SELECT * FROM picture ORDER BY RANDOM() LIMIT 2';
$result = mysql_query($query);
$rec = mysql_fetch_array( $result, MYSQL_ASSOC );

echo $rec['pic_location'];

I want to get the next 3 image also so that i can show that these 2 images will come up in full screen when the next button is clicked. One will Appear as a full size and other as a thumbnail. How do i decode the response from the Ajax ?

     $(document).ready(function() {
$(".goButton").click(function() {
   var dir =  $(this).attr("id");

   var imId = $(".theImage").attr("id");
   $.ajax({
      url: "viewnew.php",
      data: {
         current_image: imId,
         direction    : dir
      },
      success: function(ret) {
          var arr = eval(ret);
         alert("first: " + arr[0] + ", second: " + arr[1]);


         if ('prev' == dir) {
            imId ++;
         } else {
            imId --;
         }
         $("#theImage").attr("id", imId);
      }
   });

});
});

    Not tested, but I think it should work. (This code assumes PHP returns the json_encode()‘ed array)
