Gumlet WordPress Integration Guide

Please follow the these simple instructions closely and your site should have optimised images in no time.

1. Create Account

Please create a Gumlet account by signing up and login to your Gumlet account.

2. Add a WordPress Source

We need to know where to fetch the original images for optimisation. Click the "+ Add WordPress source" button to reach the following screen.

First important input you need to provide us your WordPress URL. Please open the site where you want to implement Gumlet in a new browser tab ▶️ Copy the URL from the address bar ▶️ And paste in the WordPress URL box.

Doing it this way will ensure that this critical step is completed correctly. As some sites have URL format like https://www.example.com and others have https://example.com. Both are different and it is important to capture the correct URL here.

Second input is the Gumlet subdomain that you create. Here you can enter any name that you see fit for your website. Please note this subdomain as it will be required in the next step. Your images will be delivered via https://subdomain.gumlet.com/path/to/image.jpg like URL.

Kindly note that the choice of this subdomain will not have any impact on your site SEO. Gumlet adds canonical link header to tell the search engines that the original image belongs to your website and not Gumlet.com. This functionality is well supported by Google (Read more: Google) and popular in the SEO landscape. It is also supported by lots of other WP plugins like ShortPixel.

After above information added, please click Next button and you will be taken to parameters screen. These options are for advanced use cases only. Please leave the settings as it is and click Save button to create a WordPress source.

Once above steps are complete, your image source is ready.

For Advanced use cases only

If your original images are not being served from your main domain. Instead images are stored in Amazon S3 or Wasabi Storage, please follow this guide for source creation.

3. Install and Configure Plugin

For Gumlet to work properly in is very important that all other lazy load, image optimisation or image caching plugins are deactivated. As Gumlet takes care of all of these functionalities in one go, any other active plugin would create interference and prevent Gumlet from working.

Some popular themes like Brizy and Divi have have inbuilt lazy load, so please check your theme and disable these option. If you are using a caching plugin like WP Rocket please disable lazy load from it and exclude image file types form caching.

Once other lazy load and image optimisation plugins are disabled. Install and activate Gumlet Plugin on your WordPress.

Go to Plugins > Gumlet Plugin > Settings on your WordPress dashboard where you will see the below plugin settings screen.

Enter the subdomain created in Step 2 in Gumlet Source field. Please make sure it is entered in https://example.gumlet.com format.

Heads up! Do not enter Gumlet source in https://www.example.gumlet.com format.

Kindly leave Current Image Domain field blank and other settings unchanged.


Please save the settings and clear WordPress cache and you are done!
