How ImageEngine Works
This plugin rewrites your WordPress site’s image URLs to include the ImageEngine Delivery Address you receive when you sign up for an ImageEngine account. This rewrite will allow ImageEngine to optimise and deliver the images on the fly. After configuring and enabling the plug in, image are delivered this way:
- When a visitor requests an image, ImageEngine CDN servers use client hints or device detection to identify the requesting device- and browser characteristics.
- Based on the browser characteristics, ImageEngine will resize, compress and convert images to the optimal format like WebP, JPEG2000, or AVIF.
- The optimized image is delivered from the nearest ImageEngine CDN region. Subsequent requests are served instantly with WebP, JPEG 2000, or AVIF images and stored on ImageEngine’s global CDN.

What is an Image CDN
An Image CDN is just like a normal CDN, but with built in features to optimize images. With ImageEngine, this optimization happens automatically, according to the capabilities of the device or browser.
What kinds of files can I serve through the CDN?
wp-includes) are static and are safe to serve. If you include other directories, be sure to exclude any files types that are not static.
Can I use this plugin if my site is not yet on the public internet?
If the CDN cannot contact your server over the internet, it will not be able to serve your content. Your site needs to be publicly reachable on the web. You can configure the plugin, but you should leave it disabled until your site is publicly accessible. Some CDNs, like ImageEngine support fetching assets from behind password-protected sites and other origins like AWS S3. These options may work for sites that are not publicly accessible.
