Online platforms, databases, and galleries offering fine art for content creators are not all reliable, legal, or ethical. Therefore, it's important to look for sources that have a clear and transparent policy on copyright, license, and attribution of the fine art they provide. Additionally, the sources should have a high-quality, diverse, and curated collection of fine art that meets your needs. Some reputable sources include the Google Arts and Culture platform, Creative Commons Search engine, and Wikimedia Commons repository. The Google Arts and Culture platform features thousands of artworks from museums and cultural institutions around the world; however, you must follow the attribution and license requirements of each artwork. The Creative Commons Search engine allows users to search for artworks licensed under various Creative Commons licenses with filters such as license type, source, format, and keyword. Meanwhile, the Wikimedia Commons repository hosts over 75 million media files that are in the public domain or freely licensed; you can use them for any purpose as long as you attribute the author and source.
