In reply to Ryan Hellyer.

We do try to be as clear as possible with what our services do -- although there's always room for improvement.

We do state very clearly that Photon is a content delivery network (free!) for images that we use to serve your images in an optimised form instead of using the host's bandwidth and resources. For many users this is a big plus not only because of speed but also because you won't eat up your bandwidth allocation if traffic spikes since images can be quite large.

We take it as implied that if you opt in to use a CDN then we need to upload your images to our servers. That's the only way it can work :-)
