matching different images

hi, i am trying to match images. this one works fine only with same images but i want to match unidentical images based on their id or src
below is the working code for similar images

<div id="playCards">
                    <table>
                        <tr>
                            <td><img id="1a" src="http://oi47.tinypic.com/8winhl.jpg" /></td>
                            <td><img id="2a" src="http://i47.tinypic.com/35cmsg5.jpg" /></td>
                            <td><img id="3a" src="http://i49.tinypic.com/f1xdzm.jpg" /></td>
                           
                        </tr>
                        <tr>
                           
                            <td><img id="1b" src="http://oi47.tinypic.com/8winhl.jpg" /></td>
                            <td><img id="3b" src="http://i47.tinypic.com/35cmsg5.jpg" /></td>
                            <td><img id="2b" src="http://i49.tinypic.com/f1xdzm.jpg" /></td>
                        </tr>
                    </table>
                </div>
 
 
<script>
 
var found = 0;
var last = null;
(function(d){d.fn.shuffle=function(c){c=[];return this.each(function(){c.push(d(this).clone(true))}).each(function(a,B)/>{d(B)/>.replaceWith(c[a=Math.floor(Math.random()*c.length)]);c.splice(a,1)})};d.shuffle=function(a){return d(a).shuffle()}})(jQuery);
 
$(document).ready(function(){
   
    $('#playCards td').shuffle();
 
    $('img').each(function(index){
      $(this).attr('id','img-' + index);
    });   
   
    $('img').click(function(){
      if( last ) {
        if( ($(this).attr('src') == last.attr('src')) && ($(this).attr('id') != last.attr('id')) ) {
          $(this).css('visibility', 'hidden');
          last.css('visibility', 'hidden');
          found++;
        }
        if (found == 3) {
        alert('Here is your sticker!');
        window.location.href = "#play1";
        //reset found to 0
        location.reload();
        }
        last = null;
      } else {
        last = $(this);
      }
    });
   
}); //end ready
