Unsplash has been on my The Best Online Sources For Images list for quite awhile. It has tens of thousands of images that can be used for free – commercially or for educational purposes – without having to provide any attribution to the photographer (though, of course, it’s still a nice thing to do).
Until relatively recently, however, it didn’t have a search feature.
Today, they unveiled a great one, and it’s super-fast.
I’m still going to go with Photos For Class as my favorite free image site (see “Photos For Class” Is My Favorite Site For Finding Images), but Unsplash is a close second.
