This is a BIG (and breaking) change. It would cost the company ten minutes to send out a proper notice. Burying these changes deep down in a terms and conditions document is bad behaviour.

Proper way to do this would be to: - Notify your customers about the change in an easy to read email and/or message when you log in. - Only apply the change to new uploads at first, then it's easily discoverable and handled by users. Inform them that you plan to do this for all hosted images. - Apply the change to older uploads a few months later.

Hiding and rushing it just makes people angry. They won't pay if they feel you tricked them.
