We have been experimenting with Amazon Cloudfront for Manula for a few months already, but today we switched over permanently. As of today, all images in your manuals are delivered through Amazon’s Cloudfront world-wide content delivery network.
This will result in faster downloads of all manual images for your readers. Once an image has been cached by a Cloudfront server near your (or your reader’s) location, it will be served super fast to other users in the same area.
Nothing to do on your end, just enjoy the performance improvements.
