Shorten your URLs and hide parts of your original image urls/repositories to protect your original images from being downloaded.
Specify which domains your Cloudimage token can download original images from. You can limit the list to few domains that you own to make sure no one uses your token on his or her URLs.
Sign your Cloudimage URLs with an SHA hash to prevent someone else from using your Cloudimage token.
With this feature, you can sign only part of the url which will allow you to add more parameters to the URL while protecting the sealed ones.
