I love the ability to easily find art I can use, saving me hours of searching for sources and trawling through weird licensing agreements!
Great content for filling in the white space in documents. I used a few pieces of art from this and other resources to add flavor and a visual aspect to the written text in my DMG product.
Even though the quality isn't always great I'm glad these are available and they're good for covers and things like that
It was hit and miss. Some of the images were divided into two for some reason. Didn't find it that useful.
