 //Adjust the image reel to its new size
 $(".image_reel").css({'width' : imageReelWidth});

 //Paging + Slider Function
 rotate = function(){
     var triggerID = $active.attr("rel") - 1; //Get number of times to slide
     var image_reelPosition = triggerID * imageWidth; //Determines the distance the image reel needs to slide

     $(".paging a").removeClass('active'); //Remove all active class
     $active.addClass('active'); //Add active class (the $active is declared in the rotateSwitch function)

     play = setInterval(function(){ //Set timer - this will repeat itself every 3 seconds
         $active = $('.paging a.active').next();
         if ( $active.length === 0) { //If paging reaches the end...
             $active = $('.paging a:first'); //go back to first

Note: The script code red at the top, if the template you've installed the script it any series, the script code that should not be included, only one jquery contained in a template if there are two or more will clash and one of its functions is not the way .. numposts : 6; is the number of posts that appear on the slider
  • Now you want to put it where the slider, if you want to put in the right sidebar at the top as shown in the demo. Find code <divid='sidebar-wrapper'> sidebar or wrapping existing code in your template, then put the following code before or above <divid='sidebar-wrapper'> :

<div class='sompret-wrapper'>
<div class='sompret'>
<div class='image_reel'>
<script>
document.write(&quot;&lt;script src=\&quot;/feeds/posts/default?max-results=&quot;+numposts1+&quot;&amp;orderby=published&amp;alt=json-in-script&amp;callback=showrecentposts2\&quot;&gt;&lt;\/script&gt;&quot;);
</script></div>
<div class='description'>
<script>      
document.write(&quot;&lt;script src=\&quot;/feeds/posts/default?max-results=&quot;+numposts1+&quot;&amp;orderby=published&amp;alt=json-in-script&amp;callback=showrecentposts1\&quot;&gt;&lt;\/script&gt;&quot;);
</script>
</div>
</div>
<div class='paging'>
<a href='#' rel='1'/>
<a href='#' rel='2'/>
<a href='#' rel='3'/>
<a href='#' rel='4'/>
<a href='#' rel='5'/>
<a href='#' rel='6'/>
</div>

Slider above you can modify yourself, you can also use it for drawing horizontal slider (not necessarily vertical) try to be more creative by changing the length and width of existing in this tutorial or add ribbon decoration such as seen in this demo , so it looks to be more interesting. That was a tutorial to make a simple slider this time, if there are less obvious please leave in the comments field below.
