Hai everyone today I will tel you How to add an automatic read more button in Blogger wit thumanails.
So here is the steps to be followed by you to add an auto Read more button with thumbnails.
                                       
Steps to apply auto read more button.

First go to Template section and them click on Edit Html.
If you want to back you template  than you can otherwise forget it.
Find the code :-<data:post.body/> 
 So what you have to do is to replace the code with this coed OK!

<b:if cond='data:blog.pageType == "static_page"'>
<data:post.body/>
<b:else/>

<b:if cond='data:blog.pageType != "item"'>

<div expr:id='"summary" + data:post.id'><data:post.body/></div>
<script type='text/javascript'>createSummaryAndThumb("summary<data:post.id/>");
</script> <span class='rmlink' style='float:right;padding-top:20px;'><a expr:href='data:post.url'>Read more...</a></span>

</b:if>
<b:if cond='data:blog.pageType == "item"'><data:post.body/></b:if>
</b:if>

Now search for the </head> tag and paste the code before that  I said before that.

<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
