When an image is defined as RM mode, the license to use obtained by the user is restricted by frequency, time, space, usage and other conditions. Each time a customer uses such an image, he must obtain the license to use. The authorization price is calculated in accordance with the times the end-customer has used, usage, geography, life span, life cycle, size of image and other factors. End-users also have the opportunity to buy out the right to use an image.

      When an image is defined as RF mode, the user obtains a non-exclusive license to use. When a user purchases the license to use, his use of images will not be restricted by frequency, time, space and usage. The authorization price of an RF product depends largely on image size rather than specific usages. Once a user has purchased RF image products, he can use the images for multi-time with multi-usages without paying any additional costs (of course, illegal use is prohibited). RF image products can only be used by the purchasers themselves. They can not be transfered or re-sold, nor can their exclusive right to use be bought out.
