Shutterstock doesn't sell images. Shutterstock sells licenses to use images.
When they sell a license to one of your images you get some amount of the use license fee.
So what marketing and promotion are you doing, or planning to do, to drive eyes to your images at Shutterstock?
To make significant money from RF licensing you need to have several thousand images, in a broad range of genres, on offer.
