It's such a hassle to find high quality free stock photos. Most sites lump them in with the commerical license photos so you have to spend hours sifting through them. It also always seems to be the most expensive one that you actually want. Others don't offer any way to search or categorize them. Today, we have a few really high quality, easy to use, free stock photo sites which will keep your projects looking sharp.
Of all the free stock photo sites, Gratisography has the most original and interesting photos. You won't see only landscapes or boring guys sitting with their laptops here. Photos are by Ryan McGuire and are really quirky and fun. Photos are updated regularly and free for personal and commercial use.
Most of the free stock photo sites out there are not searchable. If you want a photo, you have to infinity scroll through everything they have. In steps Stock-Up. This is a site that aggregates many free stock photography sites and makes them searchable and downloadable all in one place. The interface is really clean and easy to use.
Currently it provides searchable stock photos for:
Unsplash - 10 new photos added every 10 days
Splitshire - Really unique high quality photos
LifeOfPix - Updated regularly
New Old Stock - Vintage Photos from the Public Archives
Startup Stock - Primarily photos involving technology, mac books, and startup office space.
Jay Mantri - 7 new photos every Thursday
Skitterphoto - Public domain photos
Hopefully this site will continue to grow and become a central location for free stock photography. There are many sites scattered about offering free photos, but it's nice to have them all in one place.
