GRATISOGRAPHY describes itself as a site with "Free high-resolution pictures you can use on your personal and commercial projects". The images are credited to Ryan McGuire, "an avid photographer that enjoys capturing slightly eclectic images". Gratisography says that all of the images on the site are free of copyright restrictions and the Creative Commons tool for generating a CC0 license is linked to....but no actual CC licenses for individual images seem to have been created. Thus these images are probably not 'public domain' despite Mr. McGuire's clear intent to make them so; consequently, if you decide to reuse some of Mr. McGuire's images you should let him know through his personal website. New pictures are added weekly.
