Image repositories for e-Learning

The following is an annotated list of online repositories containing images which can be used without cost or restriction for educational purposes. There are sometimes conditions on using images, which should be consulted prior to use - for example, attribution. Many of these repositories licence their contents under Creative Commons as Open Educational Resources (OER). The sole criterion in evaluating image sources below is: are the images cost-free, and usable without restriction, for educational purposes

NB: School colleagues should consult the extensive and official Copyright Guidelines on the School Intranet.
