There are a number of internet sources where you can find good quality, copyright free images, charts, tables and figures to use in your assignments and other academic work.
Remember, in your assignment you should always acknowledge the original source of an image (as you would a written quotation or idea), even if there is no legal requirement to do so. Click the title links below to access these sources
Wikimedia Commons
Wikimedia Commons contains over 55 million freely usable media files (videos and sounds as well as images) under a variety of licences. Make sure you are aware of how an image is licensed and what you are permitted to do with it – e.g. many images are free to be reused but will still require you to acknowledge the original source. Some licenses will allow you to modify an image.
With images that are in the Public Domain, even though they are free to use, for academic purposes you should still credit the original source.
