The 12 images and the stories behind them can be downloaded and used as a 2014 wallpaper calendar on desktop and laptop computers, or as background images on phones and other portable devices. Several resolutions and device-specific versions have been provided for your convenience.
Each set of images is provided in *.zip format or may be downloaded individually (.jpg files). You may need to right-click and choose "Save Link As..." or "Save Target As..." to download the *.zip file to your desktop before opening and extracting the individual image files. Please note: due to size, these files may take several minutes to download.
A downloadable PDF of the calendar is also available.
