What's the ugliest thing on the internet you ask?
It's true. They are usually so incredibly cheesy and sterile that using them, and having TO PAY to use them sends a shiver down the spine.
That's why discovering Unsplash was the greatest day in the history of all things Stock Photography related. All the photos on Unsplash are free to use, don't require a license and are crazy beautiful. Yea the database isn't huge but we'll take quality over quantity any day.
