For my authoritative DNS I use CloudFlare NS. The caching service would bypass images with the extensions shown in your (wp2Cloud plugin) screenshots like: /wp2cloud/wp2cloud.php?weblob...daisy.jpg. CloudFlare would continue to cache css, js... and provide it's IP security services.
Inspecting images on your site blog (oblaksoft) the images in the source look like normal WP uploads. Is there a demo site showing the use of the Google Cloud paired with ClouSE ?
Just getting my head around all the options before deciding how to dive in.
