Integration steps

Here is what you need to do:

Step 1: Configure origin in ImageKit.io dashboard

Configure origin based on where your images are stored. For example, Amazon S3 bucket origin or web server.

Step 2: Fetch image through ImageKit.io endpoint

Let's quickly fetch the image using ImageKit.io URL-endpoint and see if it's working.

When you add the first origin in your account, it automatically becomes accessible through the default URL-endpoint, that is https://ik.imagekit.io/your_imagekit_id. Otherwise, you will have to configure an existing URL endpoint or create a new one to fetch images from this newly added origin.

If your old image URL was https://www.example.com/wp-content/uploads/image.jpg, then the same image should be accessible through ImageKit.io URL-endpoint, i.e., https://ik.imagekit.io/your_imagekit_id/wp-content/uploads/image.jpg

Step 3: Install and configure ImageKit.io plugin in WordPress

  1. Install and activate ImageKit.io WordPress plugin.

  2. Go to SettingsImageKit.io setting.

  3. Fill the ImageKit URL endpoint (or CNAME) with your_imagekit_url_endpoint. Copy and paste from the ImageKit.io dashboard.

  4. Click "Save changes" button.

  5. Flush cache, if any.

Now all the image files under theme directory on your WordPress site (with extensions matching one of gif, png, jpg, jpeg, bmp, ico, webp) will be loaded via ImageKit.io.

Using ImageKit.io to deliver non-image static assets like JS or CSS

By default, ImageKit.io plugin is configured to load only image files through ImageKit.io URL-endpoint, but you can override this setting by changing the value in File types field.

Enter the semicolon-separated list to allow JS and CSS files as well, for example - *.js;*.css;*.gif;*.png;*.jpg;*.jpeg;*.bmp;*.ico;*.webp

Loading files from custom directories outside theme folder

By default ImageKit.io WordPress plugin loads files from theme folder. But you can override this setting by adding new paths in Custom files field. All the values in this field are separated by a new line. Wildcard (*) is allowed.

Restrict loading specific files through ImageKit.io

There could be a case where you don't want the files on a specific path or pattern to be loaded via ImageKit.io. This can be done by setting the right values in Rejected files field. All the values in this field are separated by a new line. Wildcard (*) is allowed.

For example, we want to avoid loading captcha assets through ImageKit.io, so we can enter wp-content/uploads/wpcf7_captcha/* under rejected files, as shown in the screenshot above.
