Let's take a look at how it will look like in this demo blog.
If you have a wallpaper or photo blog that would benefit from displaying a thumbnail grid style layout, look no further. Here's how you can add Grid (gallery) View to Blogger posts.
Adding Grid (Gallery) View to Blogger Posts
Step 1. Log into your Blogger account and go to "Template", then click on the "Edit HTML" button
Step 2. Click anywhere inside the code area and press the CTRL + F keys to open the search box
Step 3. Type </head> inside the search box and hit Enter to find it.
Step 4. Just above the </head> tag, add the following script and CSS codes:
<script src='http://code.jquery.com/jquery-1.9.1.js'/>Note: If there's too much space below the posts, modify the 170 height value.
<b:if cond='data:blog.pageType != "item"'><b:if cond='data:blog.pageType != "static_page"'>
<script type='text/javascript'>//<![CDATA[
function hideLightbox(){for(var a=document.getElementsByTagName("img"),b=0;b<a.length;++b)a[b].onmouseover=function(){var a=this.parentNode.innerHTML;this.parentNode.innerHTML=a,this.onmouseover=null}}$(document).ready(function(){var a=200,b=170,c="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjmJomWk-K7nvT_RL4fojTZfeYScFDex3sndqOMkazQXMbKfxNEiUbZKHLkT7rWdURPiRGIJ3_TIkZVM9HxmYmVFPAOL9VN874XoT-XaoHqxfezZ8d__FG9K25Ia84eqiDdUr6Z0-uePXw/w500-c-h330/no-thumb.png",d=1;$(".post-body").each(function(e,f){var f=$(f),g=$(f).find("img").first(),h=f.parent().find("h3 a"),i=h.attr("href"),j=h.text();if($(h).remove(),f.empty(),g.attr("src")){var k=g.attr("height"),l=g.attr("width"),m=$(g).parent();if(f.append(m),d)g.attr({src:g.attr("src").replace(/s\B\d{3,4}/,"w500-h330-c")}),g.removeAttr("width").removeAttr("height");else{g.attr({src:g.attr("src").replace(/s\B\d{3,4}/,"s"+a)}),g.removeAttr("width");var n=(k/l*a).toFixed(0);g.attr("height",n)}}else var g=$("<img>").attr("src",c),m=$("<a>").append(g).appendTo(f);m.attr("href",i).css("clear","none").css("margin-left","0").css("margin-right","0").addClass("postThumbnail");var o=$("<div>").prepend(j).css("opacity","0.9").css("filter","alpha(opacity=0.9)").appendTo(m);o.height();o.css("margin-top","-28px"),f.css("height",b).css("overflow","hidden")}),$("#blog-pager").css("clear","both")}),window.addEventListener?window.addEventListener("load",hideLightbox,void 0):window.attachEvent("onload",hideLightbox);
