Display Blogger Posts in Grid View with Thumbnails

Grid View with Thumbnails is a script for self-hosted Blogger blogs which will display blog posts as a thumbnail grid of images in homepage and archive pages. Instead of sending your blog visitors to a page that displays all the posts in full length with a large image which takes up too much space and requires too much scrolling, now you could have a clean page that displays a gallery grid, with thumbnails and post titles, linking back to the source post for that thumbnail. Let's take a look at what it could look like in this demo blog.

grid view on blogger posts

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 in to your Blogger account and go to Template > click on the Edit HTML button

blogger template html

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 style:
<script src="http://code.jquery.com/jquery-1.9.1.js"></script>
<script src="http://code.jquery.com/jquery-migrate-1.1.0.js"></script>

Note:
- If you want to make the post thumbnails larger, modify the 200 (width) and 170 (height) values in blue
- To change the default thumbnail for when there are no images, replace the URL in red with your own.

Step 5. Click on the Save template button to save the changes and View your blog. Now you should have a nice grid view on your Blogger posts. Enjoy!
