This blog - Wide Info Blog provides blogger tips, tricks & tutorials. Previously we have discussed - Create a Custom Static Home Page in Blogger. Today, we are going to discuss about auto read more or post expert with thumbnails in blogger.

Steps for adding Auto Read More with thumbnails in Blogger. Before you start, backup your blogger template first.

Step - 1. Login into your blogger account & select the blog to which you want to add Auto Read More option. Now, click on "Edit HTML" under "Template" tab. Search for </head> using ctrl+F & paste the following code just before / above  </head>  as shown below.

Code 1 :

<script type='text/javascript'>

posts_no_thumb_sum = 490;

posts_thumb_sum = 400;

img_thumb_height = 160;

img_thumb_width = 180;

</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, pURL, pTITLE){

var div = document.getElementById(pID);

var imgtag = "";

var img = div.getElementsByTagName("img");

var summ = posts_no_thumb_sum;

if(img.length>=1) {

imgtag = '<span class="posts-thumb" style="float:left; margin-right: 10px;"><a href="'+ pURL +'" title="'+ pTITLE+'"><img src="'+img[0].src+'" width="'+img_thumb_width+'px" height="'+img_thumb_height+'px" /></a></span>';

summ = posts_thumb_sum;

}

var summary = imgtag + '<div>' + removeHtmlTag(div.innerHTML,summ) + '</div>';

div.innerHTML = summary;

}

//]]>

</script>

<b:if cond='data:blog.pageType != &quot;static_page&quot;'>

<b:if cond='data:blog.pageType != &quot;item&quot;'>

<style type='text/css'>

.post-footer {display: none;}

.post {margin-bottom: 10px; border-bottom: 1px dotted #E6E6E6; padding-bottom: 20px;}

 .readmore a {text-decoration: none; }

</style>

</b:if>

</b:if>

Now Save your template & proceed to the step - 2.

Step - 2. Now again search for <data:post.body/> code in your template. Now, replace this <data:post.body/> with the code given below.

Note :  When you will search <data:post.body/>, you will find this more than once but you need to stop at second. If doesn't work, try replacing third one  -  as shown below.

Code 2 :

<b:if cond='data:blog.pageType != &quot;static_page&quot;'>

<b:if cond='data:blog.pageType != &quot;item&quot;'>

<div expr:id='&quot;summary&quot; + data:post.id'><data:post.body/></div>

<script type='text/javascript'>createSummaryAndThumb(&quot;summary<data:post.id/>&quot;,&quot;<data:post.url/>&quot;,&quot;<data:post.title/>&quot;);</script>

 <span class='readmore' style='float:right;'><a expr:href='data:post.url'>Read More &#187;</a></span></b:if></b:if>

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

<b:if cond='data:blog.pageType == &quot;static_page&quot;'><data:post.body/></b:if>

Now Save your template & enjoy. :)

Note :   In code 1, you will see some parameters like  490, 400, 160 & 180. They are the summary & post image's  height, width. You can change them according to your requirement.
