These are intended for use on public PCs, but can be also used elsewhere, and have a resolution of 1920 x 1200 pixel.</p> <p>These images are at your disposal and can be freely used within CERN. For usage outside CERN, please respect the copyrights of the images. While the images from Microsoft and Yale University can be used when keeping the included attribution, separate licenses must be obtained from <a href="http://www.bigstock.com">Bigstock.com</a>. In any case, CERN appreciates visible attribution, too.</p> <p>In order to use one, please copy/paste them in to the "C:\Windows\System32\Oobe\info\backgrounds" folder (you might need to create the "info\backgrounds" part) and rename it to "backgroundDefault.jpg".
