Hello,
While developing our latest new WordPress Theme, adding images to the online demo i have seen decreased performance in the site loading . Obliviously images have caused this website slowdown. So i tested the website with Google Page Speed and the result was catastrophic only 24 point to 100. The major problem was with images that are so large. After installing WP Super Cache Plugin and WPSMUSH.IT the performance it was better but not enough so i thought to serve my images through a CDN image server.
There are lot of premium CDN services and after investigated a lot, i found photon CDN offered by WordPress Creators (Automatic). The service is offered with Jetpack plugin and it is totally free. Yes Jetpack offer a free CDN for WordPress. This is a great news for me as theme developer. Launching themes constantly which every installation need a new CDN to be purchased can be expensive.
Now let me explain how to use JetPack free CDN service.
Install Jetpack from within WordPress itself. Log in to your site and head to your dashboard, click on the Plugins > click “Add New.” Search for “Jetpack,” and you’ll find the latest version and be able to install it by clicking the “Install Now” link.
After installation it was finished click on the Jetpack > Settings > Go on Media and Check On Speed up images and photos option.
If you want to maintain other features activated you are free to use them. I recommend to use some of them because are free and very useful.
After click on Save Settings your CDN is active. Try to check your website speed with Google Page Speed and you will see lot of improvements.
To check if your CDN is activated go on your website with Google Chrome and click on a image with right button of your mouse select Inspect Element check the link of your image. If you will see a code like this below with wp.com domain means your CDN is activated.

Its totally free and easy.
Enjoy!
