How To Add Automatic Read More With Thumbnail For Blogger

1. Login To Your Blogger Dashboard--> Design--> Edit HTML
2. Tick on "Expand Widget Templates"
3. Find this code </head> and paste the following section of code immediately before it:

<script type='text/javascript'>var thumbnail_mode = "no-float" ;
summary_noimg = 430;
summary_img = 340;
img_thumb_height = 100;
img_thumb_width = 120;
</script>
<script type='text/javascript'>
//<![CDATA[
function removeHtmlTag(strx,chop){
if(strx.indexOf("<")!=-1)
{
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;
while(strx.charAt(chop-1)!=' ' && strx.indexOf(' ',chop)!=-1) chop++;
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(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>';
summ = summary_img;
}
var summary = imgtag + '<div>' + removeHtmlTag(div.innerHTML,summ) + '</div>';
div.innerHTML = summary;
}
//]]></script>

Note:
summary_ noimg= 430;     --> The length of the summery if the post does not have a thumbnail.
summary_img = 340;       --> The length of the summery if there is an image in the post that will be converted into a thumbnail.
null_thumb_height = 120; --> The height in pixels of the thumbnail.
null_thumb_width = 120;  --> The width in pixels of the thumbnail.

4. Now, search for <data:post.body/> and Replace <data:post.body/> With The Code Below

<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>
<div style='clear: both;'/>
<span class='rmlink' style='font-weight:bold;padding:5px;float:right;text-align:right;'><a expr:href='data:post.url' >Read more ... </a></span>
</b:if>
