I have heard of shutter stock, I wasn't aware it was a site that pays artists and photographers.There are a lot of platforms where you can put your digital art or digital photography for sale. The sites I can recommend you is Fine Art America and Shutter Stock. These sites are legit and has been paying the artists and photographers since a long time. Since I am not an artist or photographer, I have not tried these sites, though.
Thanks for the Information. I would recommend it to a photographer friend of mine.
