Jetpack is nothing if not a fairly divisive plugin in the WordPress community. At this point I’m sure we’ve all had more than a couple of conversations about its positive features and its more frustrating ones. With Jetpack 2.0, though, the new Photon feature may prove to be one of the more impressive offerings of the bunch for users and developers.
Photon, when enabled, will filter through the site’s content and, if the images are local to the site, pass them off to WordPress.com and serve them via their content delivery network. So, for example, the post image above would be served from the following URL: http://i0.wp.com/original-image-url.png?resize=600.
For the average WordPress user, getting this going only takes them installing Jetpack and turning this feature on. I’m not familiar with every CDN service out there, but this sounds like the easiest free way anyone can serve up their images from a CDN. Less taxing on the site’s host, likely faster page loads, and all without the user needing to learn a lot about the service or the setup process.
