You can use the Crypko Images stored in your slot for commercial purposes by enrolling in the Premium Plan.
Also, you can purchase a commercial license for individual Crypko Images stored in your slot regardless of the plan you have enrolled in. The Crypko Images for which you purchased a commercial license can be used commercially as long as the image is stored in your slot.
In all cases, no fees will be refunded for reasons, such as the image was not actually used for commercial purposes.
