Add a Custom jQuery Lightbox To Blogger

If you are not satisfied with the default Lightbox set up by Blogger, here's another cool way to show off your pictures. In case you missed it, I have already shown in one of my posts how to customize the Blogger Lightbox by changing the background color, borders or the text color. This tutorial will show you how to replace it entirely with a cool jQuery Lightbox plugin that is very popular among bloggers.

What this Lightbox does is to display a larger versions of the images that will pop-up into a larger box once we click on them, and allows us to easily navigate through that set of photos by using the previous and next buttons.

To see how it works, visit the demo blog and click on any picture to enlarge it.

Adding jQuery Lightbox to Blogger

Step 1. From your Blogger Dashboard, click on "Theme" > "Edit HTML".

Step 2. Click anywhere on the code area and press the CTRL + F keys to open the search box, then paste the following tag inside the search box and hit Enter to find it:

]]></b:skin>

Step 3. Choose one of the Lighbox styles from below and paste the CSS code just above the ]]></b:skin> tag:

Step 5. Click on the "Save theme" button to save the changes.

The final step is to disable the original Blogger Lightbox so that it doesn't interfere with this one that we just added: go to "Settings" > "Posts and comments" and you will see the "Showcase images with Lightbox" section on the right side > select "No" and click on the "Save settings" button on the upper right side.

Now, view your blog and click on any image to see the Custom jQuery Lightbox for Blogger in action. Enjoy!
