Pexels site is probably the largest photo directory with over 50.000 photos + 2,3000 more are being added each month. If you ask me, way too much for my taste, I think I could spend hours picking the right one. That doesn’t mean that there’s something wrong with their photos, just, I’m hard when it comes to making decisions. Pexels is founded in 2014 by Bruno Joseph, Ingo Joseph and Daniel Frese. This site has literally everything for everyone. An awesome resource for photographers, designers, artists, writers and other creative folks.

This is one of my favorites, CC0 licence, free for any use. Unsplash gathers a huge variety of photographers that are contributing the site on a daily basis. There you can always find something fresh and new that is not already used on hundreds of sites. If you’re a photographer, you can create your own account, start adding photos along with your site URL and get the exposure you need for your business. Their HQ photos are unique and very often better than on the similar sites online. Check out their collections
