One such term is "royalty-free images", which refers to the fact that the user only needs to pay a one-time fee for unlimited use. "Microstock photography" is another commonly used term, which refers to the fact that these images are typically low-cost and accessible to a wide audience. "Licensed images" is another alternative term used to describe stock photography, as the user must obtain the proper license to use these images for commercial purposes.
