Let's start adding it

Before adding it you should know that this widget is not fully compatible with all templates, so please make a backup before making any changes to your blogger template. Now, follow these steps:

1. If you are using the old Blogger interface: 

• Go to Dashboard - Design - Edit HTML - (make a backup) Expand Widget Template 

If you are using the new Blogger interface: 

• Go to Dashboard - Template - Edit HTML - Proceed - (make a backup) Expand Widget Template

2. Search (CTRL + F) for this piece of code:

]]></b:skin>

3. Just above/before it, add the following code:

#gallery{position:relative;margin:0 35px 20px;width:590px;height:126px;background:#ffffff}
#gallery .belt{position:absolute;top:0;left:0;list-style-type:none}
#gallery .panel{float:left;margin:20px;width:84px;height:86px;background:url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgRenpKlBd5SwqUSOhcLGY_C7N5BZnq02ohLMhtuiC8DTnlbvYXWVHgxV8PKxWcFtnL35fMeF-it3y-9g-ympokFGoOR1jrn7Q9_h7CjqUHSsITD0rHx7tDKDZQpiRu7W5nmC47epDp8AAf/s1600/bg-slider.png) bottom center no-repeat;overflow:hidden}
#gallery .panel img{float:left;border:1px solid #DDD;margin:5px;width:72px;height:72px;background:#FFF;padding:0px}
#gallery .panel img:hover{filter:alpha(opacity=50);-moz-opacity:0.5;-khtml-opacity:0.5;opacity:0.5}

Note: you can adjust the size of gallery, changing the values in red (590 and 126).

4. Now search for the following piece of code:

</head>

5. Just above/before it, add this code:

<script src='http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js' type='text/javascript'/>
<script src='http://helplogger.googlecode.com/svn/trunk/auto-slider.js' type='text/javascript'/>
<script type='text/javascript'>

})
//]]>
</script>

Next thing to do is to place the widget just above the blogger posts.

6. Search for this code:

<b:section class='main' id='main' showaddelement='yes'>

...or if you can'find it, search for this one:

<b:section class='main' id='main' showaddelement='no'>

7. Just below it, add the following code:

<b:widget id='PopularPosts2' locked='false' title='Popular Posts' type='PopularPosts'>
<b:includable id='main'>
<b:if cond='data:blog.url == data:blog.homepageUrl'>
<div style='margin-top:20px;margin-bottom:70px;margin-left:-20px;'>
  <div id='gallery'>
   <ul class='belt'>
    <b:loop values='data:posts' var='post'>
     <li class='panel'>
      <b:if cond='data:showThumbnails == &quot;false&quot;'>
       <b:if cond='data:showSnippets == &quot;false&quot;'>
        <a expr:href='data:post.href' expr:title='data:post.title' rel='bookmark'><data:post.title/></a>
       <b:else/>
        <div class='item-title'>
         <a expr:href='data:post.href' expr:title='data:post.title' rel='bookmark'><data:post.title/></a>
        </div>
        <div class='item-snippet'>
         <data:post.snippet/>
        </div>
       </b:if>
      <b:else/>
       <a expr:href='data:post.href' expr:title='data:post.title' rel='bookmark'>
        <b:if cond='data:post.thumbnail'>
         <img expr:alt='data:post.title' expr:src='data:post.thumbnail'/>
        <b:else/>
         <img alt='no image' src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh6axnxi9wi5dg-T6Fx1PXHLIupprtNjx8k5LJb8Xefnt6ZE1FqD4C2JqLTAIin-L7hzAkHWMjGBIWO86Xcgwurvqj3P1-2J5MxFAtTAczudiLfv1JpSn6uIofNUwEkxeJYBow1cusqPKRc/s1600/no-image.PNG'/>
        </b:if>
       </a>
      </b:if>
     </li>
    </b:loop>
   </ul>
  </div></div></b:if>
 </b:includable>
</b:widget>

Note: delete the fragments of code in blue if you want this widget to be displayed in posts pages also.
