Royalty-free images are photographs or illustrations that can be used without paying royalties or licensing fees each time they are used. Once purchased or downloaded, users can typically use these images for various purposes, such as in websites, advertisements, or presentations, without worrying about ongoing costs. These images are often available through stock photo websites, where users can browse and select from a wide range of categories. While "royalty-free" means no recurring fees, it does not imply that the images are free; users may still need to pay a one-time fee or adhere to specific usage guidelines set by the image creator or stock photo platform.
