内容范围： Creative Commons launched CC Search in 2019. It moved to WordPress and is now called Openverse, which searches more than 700 million openly licensed and public domain images and audio files. Video is reached through external sources.	内容范围： Google Images indexes the open web in general. Only part of it carries license information, so the usage rights filter narrows results to images with license data attached.	内容范围： Getty Images is a commercial agency. It sells royalty-free, rights-managed and rights-ready content, plus editorial material with its own restrictions.
Licence handling: The aggregator is built around open licences and public domain works. Openverse offers one-click attribution but does not verify licensing or attribution accuracy, so the source page must be checked.	Licence handling: The filter offers Creative Commons or Commercial and other licenses. Google sorts images using data from the hosting sites, so the filter is only as reliable as that data and a copyright may still apply.	Licence handling: Licences are contractual. Royalty-free is a one-time fee for worldwide, perpetual use, and rights-managed licences are priced by size, placement, duration and geography.
成本： Searching and reusing the listed works is free, within the terms of each licence. Attribution is usually required.	成本： Searching is free. Finding an image costs nothing, but a commercial image found this way is not free to use, and licence details link to the provider.	成本： Content must be paid for. The agreement states plainly that royalty-free does not mean there is no cost.
Legal risk and limits: Verify the licence at the original source before publishing a figure or product image. Some licences forbid modification or commercial use.	Legal risk and limits: Google advises to always confirm license information with the license provider and the host site before reuse.	Legal risk and limits: Editorial content cannot be used commercially without written permission, and uses such as machine learning training need an additional licence.
何时选择它： Choose it for illustrations, diagrams and photos in technical documentation, teaching material or reports where free reuse with credit is acceptable.	何时选择它： Choose it to survey what exists on a subject, then trace each image back to its licence holder.	何时选择它： Choose it when a project needs a guaranteed, documented licence, model and property releases, or exclusive rights.
