Stock photo is a term used to describe an image that is bought from the photographer or stock agency directly. These images are sold with the intention to sell them multiple times to different buyers for use in graphic designs, websites, digital designs, or used as a photo. This option was created so that people did not have to have a custom photo created for their use. It was an option that made photos easy to find, easy to buy and easy to use. The term stock photo is used to separate this idea of buying as you need a photo versus a photo as art, editorial or custom shots. Think of it as going to Costco for a photo versus having a photographer create a photo for you. Stock photos do have terms attached to their use that are outlined by the stock agency that sells them.
