There’s nothing better than free stock photos, except maybe high-quality free stock photos. Unsplash offers up 10 new stock photos every 10 days.
You can visit Unsplash and download the photos individually, or sign-up for the email newsletter which contains a link to download all 10 photos in a single .zip file.
All the photos offered by Unsplash are of fairly high-quality, and though it doesn’t say so, each collection of 10 images appears to be of a particular theme. The images can be used for anything you wish (personal or commercial use).
There are lots of free photo sites out there, but I really like Unsplash because the images are fairly unique in their subject matter. You’re not likely to see similar images elsewhere.
The photos available on Unsplash are submitted by people just like you. So if you have a photo you want to make available for anyone in the world to use, feel free to submit it using the link at the top of the homepage.
