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

</script>

After that, find this code: <data:post.body/>
Replace that code with following code:

<b:if cond='data:blog.pageType == "item"'>
<data:post.body/>
<b:else/>
<b:if cond='data:blog.pageType == "static_page"'>
<data:post.body/>
<b:else/>
<div expr:id='"summary" + data:post.id'><data:post.body/></div>
<script type='text/javascript'> createSummaryAndThumb("summary<data:post.id/>");
</script>
<a class='more' expr:href='data:post.url'>Read more » </a>
</b:if>
</b:if>
