autoplay between pagination

I have this code is working fine just I want to add autoplay between pagination after 10 seconds passes to the other page (interval carousel) Code :

<?php 
$gethads  = $DB_con->prepare("SELECT id,img FROM `homeads` ORDER BY id ASC");
$gethads->execute();  
if($gethads->rowCount() > 0){          
foreach ($gethads->fetchAll() as $rowH){ 
echo'
    <div class=" line-content">
     <img src="'.DIR.'uploads/'.$rowH['img'].'">  
    </div>  
';
}    
}         
?>      
<ul id="pagin">
<?php if($gethads->rowCount() > 8){ ?><a class="current" href="#">1</a> <?php } ?>
<?php if($gethads->rowCount() > 8){ ?><a href="#">2</a> <?php } ?>
<?php if($gethads->rowCount() > 16){ ?><a href="#">3</a> <?php } ?>
<?php if($gethads->rowCount() > 24){ ?><a href="#">4</a> <?php } ?>
   </ul>    
<script type="text/javascript">
    pageSize = 8;
    showPage = function(page) {
        $(".line-content").hide();
        $(".line-content").each(function(n) {
            if (n >= pageSize * (page - 1) && n < pageSize * page)
                $(this).show();
        });        
    }

    showPage(1);
    $("#pagin a").click(function() {
        $("#pagin a").removeClass("current");
        $(this).addClass("current");
        showPage(parseInt($(this).text())) 
    });
</script>
