Adding Automatic Read More Function with Thumbnails on Blogger

1. Now Login to Blogger Go to Layout > Edit HTML in your Blogger dashboard and check the "expand widget templates" box.

2. Find the closing </head> tag in your blog template, 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: In above codes you can change the numeric numbers according to your needs.

summary_noimg = 430; is post cut height without image
summary_img = 340; is post cut height with image
img_thumb_height = 100; is thumbnail image height
img_thumb_width = 120; is thumbnail image width

3.  Now find the code <data:post.body/> in your template and replace it with below codes.

<b:if cond='data:blog.pageType == &quot;static_page&quot;'><br/>
<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 "<data:post.title/>"</a></span>

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

4. Preview your template. If it's showing thumbnail with read more function on your blog posts then you can SAVE it.

Note: To show thumbnail, you should have at least one image in your blogger post and please upload the js file to your server and don't forget to change the link with yours in codes to make this hack work.
