Where can I obtain stunning free images?
The InspiringSTEM Network sets a high standard for our posts' images or what we call 'poster' images. We would prefer NOT to use copyrighted images to avoid the complexity of seeking permissions. Luckily, however, there are a number of excellent sites offering stunning, high quality and completely free to use stock photos.
All images from the following preferred sites are released under Creative Commons CC0, which makes them safe to use without asking for permission or giving credit to the artist, even for commercial purposes.
NB: All poster images should ideally be at least 1280 x 960 pixels and should be in JPG format. When downloading from the above sites, you can specify the size required.
