VecteezyThis website contains free vectors, photos, and videos. There are premium pieces for purchase, but their selection of free art is great. I like the modern feel of the work on this site. You can search by orientation, image style, number of people or age of people in the photo, and the composition of the photo (head shots, full body, etc.). Attribution is required and there are limits to the ways in which you can use the art under the free license.
