Image CDN Benefits

Hosting many images within your WordPress site slows down your sites performance and increases bandwidth. An Image CDN makes the process of serving images as seamless as possible. It increases the speed of your website by offloading images and caching static content. Image CDN’s also interpret the screen size and resolution of the device, the DPI, as well as supported image formats. In addition, an image CDN is able to dynamically render a master image to correspond with the specifications of the device.

  • Super simple and light-weight.

Choose “Automatically use Cloudinary for all Images” to create a super easy Auto-Upload feature in the Fetch API. This plugin tells Cloudinary where to find the files on our server (or on S3 or anywhere on the Internet), and it automatically downloads it from there,  thus saving it on to it’s servers the first time you ask for it, like a CDN would!


Now Cloudinary will automatically fetch and serve the images from your WordPress media library using a Cloudinary Dynamic File name.
