We all from time to time need quality photos for blog posts, PP slideshows and other documents. Here are a few free sites where you can score various photos for your next project.
Pexels is my current favorite of the free image sites. Browse their site here.
All Free Stock
All Free Stock also offers free sound effects and videos.
StockSnap has a good variety of pictures all high res, but the amount of total images is small compared to the other sites.
Pixabay has more than 1 million images and a great search feature.
