Could Apple (OS X) wallpaper be licensed for commercial use? Does anyone know who owns the Zebra Wallpaper that comes with MBP Retina Display (and Mountain Lion)? Although this is my specific task (to hunt down who owns one specific likely copyrighted image), it would be nice to know if there is a way to read the image's metadata or otherwise track in general who owns what image that ships as part of Apple's OS.
Apple and/or Apple’s licensors own the images, as stated under Apple's Software License Agreement for Mountain Lion:
