Unsplash.com is a timeline-oriented image project, where people submit their photos for free use. Do anything you want with them without need for attribution – all rights are waived by contributors carrying the licence CC Zero. You can subscribe to Unsplash and receive 10 new images every week straight to your inbox. If the current ones are anything to go by, all are of high quality and high resolution. There are a large number of botanical inspired images present – see selection below. Unlike some of the bigger stock libraries there are no categories or keywords, but that is part of the charm and if you subscribe, you never know what you are going to get.
