Make the Timber plugin work with Jetpack's Photon. Once installed, all TimberImages use Photon as a CDN and for image manipulation (eg. resize).
Photon is an image acceleration and modification service for Jetpack-connected WordPress sites. Converted images are cached automatically and served from the WordPress.com CDN. Photon is part of the Jetpack plugin and completely free.
You can find TimberPhoton in the Wordpress plugin repository.

returns a Photon URL{{post.thumbnail.src|resize(100)}}
returns a Photon URL{{post.thumbnail.src|resize(100,200)}}
returns a Photon URL
A Photon URL looks like this:
