 {
  var s = strx.split("<"); 
  for(var i=0;i<s.length;i++){ 
   if(s[i].indexOf(">")!=-1){ 
    s[i] = s[i].substring(s[i].indexOf(">")+1,s[i].length); 
   } 
  } 
  strx =  s.join(""); 
 }
 chop = (chop < strx.length-1) ? chop : strx.length-2;

 strx = strx.substring(0,chop-1); 
 return strx+'...';

function createSummaryAndThumb(pID){
 var div = document.getElementById(pID);
 var imgtag = "";
 var img = div.getElementsByTagName("img");
 var summ = summary_noimg;
        if(thumbnail_mode == "yes") {
 if(img.length>=1) { 
  imgtag = '<span style="float:left; padding:0px 10px 5px 0px;"><img src="'+img[0].src+'" width="'+img_thumb_width+'px" height="'+img_thumb_height+'px"/></span>';

Find this line: <data:post.body/> (you may find 2 lines in your template).

Replace the second <data:post.body/> you found with the following code:

<!-- Auto read more Start -->
<!-- http://www.BloggerSentral.com -->
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<data:post.body/>
<b:else/>
<b:if cond='data:blog.pageType == &quot;static_page&quot;'>
<data:post.body/>
<b:else/>
<div expr:id='&quot;summary&quot; + data:post.id'><data:post.body/></div>
<script type='text/javascript'> createSummaryAndThumb(&quot;summary<data:post.id/>&quot;);
</script>
<a class='more' expr:href='data:post.url'>Read more ...</a>
</b:if>
</b:if>
<!-- Auto read more End -->

Customizing the snippet

You can customize the read more by changing the values of the variables below:

• thumbnail_mode – set to “yes” if you want to show thumbnail with text summary. Set to other than “yes” to show only text summary.
• summary_img – specify the number of characters (including spaces) you want to show in the summary, with thumbnail.
• summary_noimg – specify the number of characters (including spaces) you want to show in the summary, when there is no thumbnail.
• img_thumb_height and img_thumb_width - specify the thumbnail height and width (in pixels).
• You can change the words “Read more” with your own by changing it in line 12 of the second part code.
