Anyone can find images on the Web, but usage rights come into play if you're looking for content that you can take and use above and beyond fair use. Site owners can use licenses to indicate if and how others can reuse content on their sites.
When searching for images in Google Drive, your search results page will include license details that specify how image search results may be used. Only select images that you have confirmed you can use in your intended context according to the license details. Your use of selected images must comply with our program policies. Include appropriate attribution if necessary. If you find images without a designation of usage rights in the search results, please report them in the help forum.
Stock images available in Google Drive are available for personal or commercial use only in Google Drive and must be used in accordance with our program policies. Images may not be offered for sale or used within templates provided to third parties. If you use stock images depicting a person in connection with a sensitive or unflattering subject, you must include this or a similar statement: "for illustrative purposes only; individual is a model."
Before reusing content that you’ve found, you should verify that your use is permitted and check the exact terms of reuse stated in the license. For example, most licenses require that you give credit to the image creator when reusing an image. Google has no way of knowing whether your use is permitted, so we aren’t making any representation that the content is actually lawfully licensed.
