从博客上的帖子摘录中删除图片标题

Question

请在我的博客博客上找到我用来生成帖子摘要（摘录）的javascript。有人可以帮我添加额外的代码，以避免在摘要/摘录中包含图像限制吗？我没有在网上找到BLOGGER的解决方案...

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 = summary_noimg;
    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+'" class="pbtthumbimg"/></a></span>';
        summ = summary_img;
    }

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