Pixabay's description of themselves is pointed and very clear. No technical jargon or fancy words to let you know that they offer free images. Their website says "Finding free images of high quality is a tedious task - due to copyright issues, attribution requirements, or simply the lack of quality. This inspired us to create Pixabay - a repository for stunning public domain pictures. Your source for free vectors, free drawings and free photos. You can use any Pixabay image without attribution in digital and printed form, even for commercial applications."
