Do you have photo skills or live in an area where images are in demand? “Stock photography websites are huge repositories of photographs, covering almost every possible subject you could imagine,” advises International Living. So how does it work? Photographers can upload their images to any one of a number of huge databases, allowing magazine editors, designers or any organization with a website to buy them. And the beauty of stock websites: Photos can be sold any number of times—so you can continue to make money without any effort.
