ImageShack Business Subscriptions can be cancelled at any time using your PayPal account:
99% uptime means that each image stored on your account is expected to be unavailable for approximately 7.2 hours per month. Subscribing to our Premium Pro service will reduce this number to less than 5 minutes per month.
Business subscribers will have their images backed up automatically. This means that if a server goes down for maintenance or experiences any issues, we will still be able to serve your files.
