The approach of pexels. All images on Pexels are free to use and come with a specific Pexels license, which basically follows the Creative Commons CC0 license. The database comes in several languages, which makes searching in other languages, again very easy.
On top of the five databases mentioned above, there is a whole load of smaller databases offering free photos that have been put together by artists and photographers. Most of them do not have a great deal of science-related images, but there are one of a kind photos you can get here and nowhere else. Some of them require an email sign-up and then they deliver you new pictures every week, others work with databases that are enlarged weekly.
Most of the above mentioned databases follow one of the Creative Common licenses. We still advise you to do your own research and check how the images derived from any of the databases above can be used as regulations may change. You always need to be aware that the producer of the image does not provide any warranties about the work, and withdraws liability for all uses of the work.
Only use pictures where the privacy rights of people shown on the footage are not affected. Crediting of the photographers is in most cases not required, but a kind gesture, certainly if you like the images and they help you make a better presentation! It is possible to get really good photographs, graphics, illustrations and videos for your next talk for free!
